* stm32 Updated flash patch to upstream (fixes missing commit)
* Removed zubaxgnss-v1_bootloader check build will not fit
Removing zubaxgnss-v1_bootloader from the check build. It is overflowing flash by 6 Bytes.

1) stm32: Fix erase sector number for microcontrolers with
more than 11 sectors
Erase a sector from the second bank cause the bit 4 of SNB being set
but never unsed, so trying to erase a sector from the first bank
was acually eraseing a sector from the second bank.
2) stm32: Make up_progmem thread safe
Writing to a flash sector while starting the erase of other sector
have a undefined behavior so lets add a [staticaly initalized]
semaphore and syncronize access to Flash registers.
3) Add workaround for flash data cache corruption on
read-while-write
This is a know hardware issue on some STM32 see the errata
of your model and if you make use of both memory banks you
should enable it.
4) Greg's cleanup
5) PX4 clean up
