84dc42c4b0 gpio: Disable USB JTAG when setting pins 18 and 19 as GPIOs on ESP32C3
When `DIS_USB_JTAG` eFuse is NOT burned (`False`), it is not possible
to set pins 18 and 19 as GPIOs. This commit solves this by manually
disabling USB JTAG when using pins 18 or 19.
The functions shall use `gpio_hal_iomux_func_sel` instead of
`PIN_FUNC_SELELECT`.

89d39308a0 bootloader: avoid printing load addresses with '0x'
Since idf_monitor decodes anything that looks like a code address and
starts with 0x, bootloader logs often get annotated with function
names such as WindowOverflow and other random and scary looking things
unrelated to the issue the user is facing. Print the addresses without
0x to avoid confusion by decoded function names. Print hexadecimal
size with 'h' suffix to distinguish it from the decimal value that
follows.

647dea9395 soc: combine xxx_caps.h into one soc_caps.h
During HAL layer refactoring and new chip bringup, we have several
caps.h for each part, to reduce the conflicts to minimum. But this is
The capabilities headers will be relataive stable once completely
written (maybe after the featues are supported by drivers).

Now ESP32 and ESP32-S2 drivers are relative stable, making it a good
time to combine all these caps.h into one soc_caps.h

This cleanup also move HAL config and pin config into separated files,
to make the responsibilities of these headers more clear. This is
helpful for the stabilities of soc_caps.h because we want to make it
public some day.

fefdee1349 bootloader: fix the WRSR format for ISSI flash chips
1. The 2nd bootloader always call `rom_spiflash_unlock()`, but never help to clear the WEL bit when exit. This may cause system unstability.

   This commit helps to clear WEL when flash configuration is done.

   **RISK:** When the app starts, it didn't have to clear the WEL before it actually write/erase. But now the very first write/erase operation should be done after a WEL clear. Though the risk is little (all the following write/erase also need to clear the WEL), we still have to test this carefully, especially for those functions used by the OTA.

2. The `rom_spiflash_unlock()` function in the patch of ESP32 may (1) trigger the QPI, (2) clear the QE or (3) fail to unlock the ISSI chips.

   Status register bitmap of ISSI chip and GD chip:

| SR | ISSI | GD25LQ32C |
| -- | ---- | --------- |
| 0  | WIP  | WIP       |
| 1  | WEL  | WEL       |
| 2  | BP0  | BP0       |
| 3  | BP1  | BP1       |
| 4  | BP2  | BP2       |
| 5  | BP3  | BP3       |
| 6  | QE   | BP4       |
| 7  | SRWD | SRP0      |
| 8  |      | SRP1      |
| 9  |      | QE        |
| 10 |      | SUS2      |
| 11 |      | LB1       |
| 12 |      | LB2       |
| 13 |      | LB3       |
| 14 |      | CMP       |
| 15 |      | SUS1      |

   QE bit of other chips are at the bit 9 of the status register (i.e. bit 1 of SR2), which should be read by RDSR2 command.

   However, the RDSR2 (35H, Read Status 2) command for chip of other vendors happens to be the QIOEN (Enter QPI mode) command of ISSI chips. When the `rom_spiflash_unlock()` function trys to read SR2, it may trigger the QPI of ISSI chips.

   Moreover, when `rom_spiflash_unlock()` try to clear the BP4 bit in the status register, QE (bit 6) of ISSI chip may be cleared by accident. Or if the ISSI chip doesn't accept WRSR command with argument of two bytes (since it only have status register of one byte), it may fail to clear the other protect bits (BP0~BP3) as expected.

   This commit makes the `rom_spiflash_unlock()` check whether the vendor is issi. if so, `rom_spiflash_unlock()` only send RDSR to read the status register, send WRSR with only 1 byte argument, and also avoid clearing the QE bit (bit 6).

3. `rom_spiflash_unlock()` always send WRSR command to clear protection bits even when there is no protection bit active. And the execution of clearing status registers, which takes about 700us, will also happen even when there's no bits cleared.

   This commit skips the clearing of status register if there is no protection bits active.

Also move the execute_flash_command to be a bootloader API; move
implementation of spi_flash_wrap_set to the bootloader

c09fdc0b09 esp32: Use package identifier to look up SPI flash/PSRAM WP Pin, unless overridden
Allows booting in QIO/QOUT mode or with PSRAM on ESP32-PICO-V3 and
ESP32-PICO-V3-O2 without any config changes.

Custom WP pins (needed for fully custom circuit boards) should still be compatible.
