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
