[PATCH v2] board: freescale: p1_p2_rdb_pc: Calculate offsets for eSDHC boot sector

[Pali Rohár]

Correctly calculate offsets between SPL and proper U-Boot when new config
option CONFIG_FSL_PREPBL_ESDHC_BOOT_SECTOR for generating eSDHC boot sector
is enabled. Otherwise SPL would not be able to boot proper U-Boot.
