bus: mhi: core: Identify Flash Programmer as a mission mode use case
MHI power up can go through an EDL to Flash Programmer path when the device has a blank NAND. In those cases, mhi_sync_power_up() can timeout waiting for a mission mode execution environment. Allow a successful power up instead by identifying Flash Programmer as a valid mission mode execution environment with a purpose to flash the device image contents.
