1. add check in the gdma driver, to prevent multiple channels connecting
to the same peripheral
2. memory copy DMA ID will occupy the peripheral's DMA ID on some ESP
targets (e.g. esp32c3/s3). We should search for a free one when
install async memcpy driver.

I'm including <hal/uart_ll.h> in my C++ application because I need to
bypass the uart driver. The inline functions in the header file fail to
compile as C++.
All of the enums need explicit casts for conversion to/from integers.

Similar to the fix in gpio lower layers, USB Serial JTAG pad should be disabled when the DM and DP pins want to be used as rtcio pins.
(cherry picked from commit de0401047c)
This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.
This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.

Internally, disable usb serial jtag DP pin's pullup when calling gpio_ll_pullup_dis and rtcio_ll_pullup_disable
At usb serial jtag setup/install, re-enable DP pin's pullup

When I2S is configured into different modes, the slot sequence varies.
This commit updates slot sequence tables and corresponding descriptions
in (both code and programming guide).
All gpio hal and ll functions input arguments gpio_num_t are changed to uint32_t type.
Validation of gpio num should be guaranteed from the driver layer.
When ESP32-C2 is paired with a 26 MHz XTAL, the systimer tick
frequency becomes equal to 26 / 2.5 = 10.4 MHz. Previously we always
assumed that systimer tick frequency is integer (and 1 MHz * power of
two, above that!).
This commit introduces a new LL macro, SYSTIMER_LL_TICKS_PER_US_DIV.
It should be set in such a way that:
1. SYSTIMER_LL_TICKS_PER_US / SYSTIMER_LL_TICKS_PER_US_DIV equals the
actual systimer tick frequency,
2. and SYSTIMER_LL_TICKS_PER_US is integer.
For ESP32-C2 this means that SYSTIMER_LL_TICKS_PER_US = 52 and
SYSTIMER_LL_TICKS_PER_US_DIV = 5.
This introduced two possible issues:
1. Overflow when multiplying systimer counter by 5
- Should not be an issue, since systimer counter is 52-bit, so
counter * 5 is no more than 55-bit.
2. The code needs to perform:
- divide by 5: when converting from microseconds to ticks
- divide by 52: when converting from ticks to microseconds
The latter potentially introduces a performance issue for the
esp_timer_get_time function.
