chenjianqiang d77c74770a bugfix(flash): add flash config in app startup 
We fixed some flash bugs in bootloader, but for the users used the old
vrsion bootloader, they can not fix these bugs via OTA, the solution is
add these updates in app startup.

These updates include:
1. SPI flash gpio matrix and drive strength configuration
2. SPI flash clock configuration
3. SPI flash read dummy configuration
4. SPI flash cs timing configuration
5. Update flash id of g_rom_flashchip

Bootloader Support Component
============================

Overview
--------

"Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app.

Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
