e0b221016f driver/mtd/at45db.c: write to page without built-in erase 
Using the FTL driver over a MTD flash device, when writing to flash, eventually the ftl_flush function is called and it does an erase (MTD_ERASE) and then the write (MTD_BWRITE). Currently, the at45db driver (at45db.c), uses a write command 0x82 ("Main Memory Page Program through Buffer 1 with Built-In Erase") that also performs a built-in erase before the write. In summary, each time a write to flash is performed, the page is erased twice before it is written, first in the FTL driver and then in the MTD driver.

This PR is to change the page writes to not use that built-in command.
