A typical scenario is: when XIP on PSRAM enabled, compiler optimization level is Os. Under certain binary layout, boot hangs and backtrace points to `esp_sleep_config_gpio_isolate`.
The root cause is that, during PSRAM initialization, it calls esp_gpio_reserve, which happens to place before the reported function. However, after call, there is no barrier before the clock adjustment in `mspi_timing_enter_low_speed_mode`. The clock gets changed when the cache is still fetching data, resulting in the corrupted data in the end of the cache line.
This commits add spi_flash_disable_cache as a barrier to make sure the cache transactions is finished before the clock switch.
fix(drivers): fixed the gptimer/MCPWM sleep retention driver support on esp32s31
Closes IDFGH-17654, IDF-15651, IDF-15647, IDF-15641, IDF-14746, IDF-15644, IDF-15646, and IDF-15649

The bootloader subproject's full Kconfig discovery resolves CONFIG_SPIRAM=y
when the parent app has it enabled, even though esp_psram is not linked
into the bootloader (the CMake gate is
'if(NOT non_os_build) if(CONFIG_SPIRAM) idf_component_optional_requires(PRIVATE esp_psram)').
Shared sources in esp_hw_support that #include esp_psram private headers
or call esp_psram functions guarded only by '#if CONFIG_SPIRAM' then fail
to compile in the bootloader with
"fatal error: esp_private/esp_psram_extram.h: No such file or directory".
Mirror the CMake gate in source guards: every '#if CONFIG_SPIRAM' block in
a bootloader-compiled source that touches esp_psram becomes
'#if !BOOTLOADER_BUILD && CONFIG_SPIRAM'. The leaked CONFIG_SPIRAM value
in the bootloader's sdkconfig.h is then harmless because every dependent
block evaluates to false.
Sites updated:
- esp_memory_utils.c: include of esp_psram_extram.h and all
esp_psram_check_ptr_addr() call sites
- port/esp32{c5,c61,p4,s31}/cpu_region_protect.c: include of
esp_psram_extram.h (inner SPIRAM_FETCH/RODATA/PRE_CONFIGURE blocks are
already inside outer !BOOTLOADER_BUILD guards)
- port/esp32{p4,s31}/pmu_sleep.c: include of esp_psram_impl.h and
esp_psram_impl_{enter,exit}_halfsleep_mode() call sites
