This patch removes the header check for UART download;
the check of checksum is not mandatory with even parity and chuck
checksum for each 256 received bytes and it is only done for
STM32 image (FSBL = TF-A BL2), not for FIT image.
This patch solve issue of duplicated 0x100 byte written with FIP header.
Fixes: 4fb7b3e108 ("stm32mp: stm32prog: add FIP header support")
