Ivan Grokhotkov f78c96a3d7 bootloader: check previously used clock frequency at run time In the situation when bootloader was compiled for 240MHz, and app was compiled for 160MHz, and the chip is a revision 0 chip, the bootloader will assume that the application has also been running at 240MHz. This will cause the chip to lock up later. Modify this to use a run time check of DPORT_CPUPERIOD_SEL, which indicates which of the PLL frequencies was used.

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.)
