Commit 8cd04c80 has added a dependency of efuse component on
esp_clk_apb_freq, however there was no definition of this function in
the bootloader context.

Closes: https://github.com/espressif/esp-idf/issues/5396
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.)
