ARM: stm32: Fix SYSRAM size on STM32MP13xx

Browse Source 
The STM32MP13xx has only 128 kiB of SYSRAM starting at address 0x2ffe0000 .
The STM32MP15xx has 256 kiB of SYSRAM starting at address 0x2ffc0000 . Make
sure both SoCs configure ARMV7_SECURE_BASE correctly . Define the SYSRAM
base in stm32.h to be consistent with the STM32MP15xx macro.
