drivers/intel/fsp2_0: Suppress OEM footer in low-battery mode

Browse source 
This patch modifies the low-battery shutdown logic to bail out early
when the system is in a low-power state. This prevents the display of
the OEM footer logo, ensuring power conservation and avoiding
unnecessary rendering alongside the low-battery icon.

BUG=b:423591644
TEST=Boot platform with `CONFIG(USE_COREBOOT_FOR_BMP_RENDERING)`
    and low battery. Verify splash appears before shutdown w/o OEM
    footer logo.
