Component: flash parameter storage on stm32h7. Fixes #15331.

Browse Source 
As per the discussion in #15331, fixed issue where stm32h7 chips
    use hardware ECC bits in program memory that disallow overwriting
    32-byte flash line that has already been written. As such,
    this change allows for a variant implementation of the flashfs system
    that uses more space in the flash entry header in order to
    allow an entire line to be reserved for erasing an entry.
