mtd: add lock fixup for AT49BV640D and AT49BV640DT chips

This patch sets the MTD_POWERUP_LOCK flag for AT49BV640D and AT49BV640DT
devices, since the devices are locked when powered up and needs to be unlocked
before interfaced.

Quote datasheet; "At power-up and reset, all sectors have their Softlock
protection mode enabled.".

Tested on AVR32 hardware platform with an AT49BV640D flash device.
