Chris Mason 3786592097 stm32/boards: Optimise flash and RAM allocation for L4 boards.

Optimisations are:
- Remove FLASH_ISR section since devices with a small flash sector erase
  size don't need special FLASH_ISR handling.  This reduces flash image by
  approx 1.5k.
- Make SRAM2 contiguous with SRAM1 where possible.
- Simplify configuration of 2k RAM buffer used for flash filesystem.

RAM changes with this commit:
- L432: stack   6k -> 10k,  bss + heap   42k ->  52k
- L476: stack  16k -> 30k,  bss + heap   80k ->  96k
- L496: stack 206k -> 16k,  bss + heap  112k -> 302k
