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

ledc_ls_timer_update is required only when CLK_DIV and DUTY_RES bits are changed.
Calling ledc_timer_rst while re-configure PWM frequency through ledc_set_freq can cause glitch in the signal
esp_light_sleep_start() will stall the other CPU via esp_ipc_isr_stall_other_cpu(). After stalling the other CPU,
will call esp_clk_... API which themselves take locks. If the other stalled CPU is holding those locks, this will
result in a deadlock.
This commit adds a workaround calling esp_clk_private_lock() to take the lock before stalling the other CPU.
esp_clk used to be protected using _lock_t (i.e., a FreeRTOS Mutex). However, esp_clk API is current called from
from critical sections, thus mutex should not be used (as they can be blocking).
This commit updates esp_clk to use spinlocks for critical sections instead.
Note: Added a small fix to exclude esp_clk.c from bootloader builds in the
legacy build system (this is already the case in CMake).
define: lock_bits = (lock->status & LOCK_MASK) >> LOCK_SHIFT; This `lock_bits` is the Bit 29-20 of the lock->status
1. spi_hdl_1:
acquire_end_core():
uint32_t status = lock_status_clear(lock, dev_handle->mask & LOCK_MASK);
Becuase this is the first `spi_hdl_1`, so after this , lock_bits == 0`b0. status == 0
2. spi_hdl_2:
acquire_core:
uint32_t status = lock_status_fetch_set(lock, dev_handle->mask & LOCK_MASK);
Then here status is 0`b0, but lock_bits == 0`b10. Because this is the `spi_hdl_2`
3. spi_hdl_2:
`acquire_core` return true, because status == 0. `spi_bus_lock_acquire_start(spi_hdl_2)` then won't block.
4. spi_hdl_2:
spi_device_polling_end(spi_hdl_2).
5. spi_hdl_1:
acquire_end_core:
status is 0, so it cleas the lock->acquiring_dev
6. spi_hdl_2:
spi_device_polling_end:
assert(handle == get_acquiring_dev(host)); Fail

update gpio_sig at `spics_out` array in each spi_periph.c of chips later than s2
then `spi_bus_add_device` can correctly distribute gpio_signals for cs_signal

`__COMPONENT_TARGETS` is evaluated very early when components and
component directories are added to the build, which means that all
components (including the ones which are in EXCLUDE_COMPONENTS) have
a build system target defined. The component manager was given the
list of all known components (derived from the list of targets), not
the list of components after EXCLUDE_COMPONENTS were processed.
Because of that, EXCLUDE_COMPONENTS didn't effectively exclude the
component from the consideration of the component manager.
