drivers/intel/fsp2_0: Release bmp_logo during READY_TO_BOOT stage

bmp_load_logo() loads the custom logo.bmp file into CBMEM. This cbmem
buffer is released after FSP-S init is complete. In certain platforms,
the logo file is displayed during PCI enumeration.  This means the logo
buffer is used after it is released. Fix this issue by releasing the
logo buffer when the coreboot has finished loading payload. During S3
scenario CBMEM is locked, bmp logo is not loaded and hence the release
is a no-op.

BUG=b:337144954
TEST=Build Skyrim BIOS Image and boot to OS. Ensure that the chromeOS
boot logo is seen without any corruption.
