Mahavir Jain 5b344610c9 bootloader_support: fix issue in memory mapping for getting app descriptor
For getting secure_version field in anti rollback case, bootloader tries
to map whole firmware partition but fails for cases where partition size
is beyond available MMU free pages capacity.

Fix here insures to map only required length upto application descriptor
size in firmware partition.

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.)
