soc/amd/common/psp_verstage: Fix pending maps
cbfs_unmap does not unmap the mapped region from the boot device. This
leads to some resource leaks eg. TLB slots in PSP. Explicitly call
rdev_munmap on the address mapped by cbfs_map.
BUG=b:240664755
TEST=Build and boot to OS in Skyrim with unsigned PSP verstage.
