soc/qualcomm/x1p42100: Update memlayout for BL31 region and realign TA region

Browse source 
TF-A feature additions have increased BL31 memory requirements. Expand
BL31 reservation from 600KB to 800KB and adjust the TA region start
address to prevent overlap. The TA region change requires FDT memory
reservation updates, which are handled in Depthcharge.This update
ensures proper memory alignment for secure firmware execution.

TEST=Created image.serial.bin and verified successful boot on X1P42100.
Basic device boot functionality with the updated memory reservation has
been validated.
