Expected behavior
when trying to program to in intranel flash using the flashIAP APIs FlashIAP ,
The program function verifies that the size is aligned to page_size.
but the page size given from the API get_page_size() is hardcoded to 0x4000.
This can be found in mbed-os\targets\TARGET_STM\TARGET_STM32F4\flash_api.c
according to the STM SDK and HAL function, the flash can be program to 8,16,32 & 64 bits
Actual behavior
Can write to flash small buffer under 0x4000 length which is the wrong behavior
Steps to reproduce
int flash
program to flash buffer with size less than 0x4000
