Michal Lenc 08bffe1c0b drivers/mtd/w25.c: ensure the device is not in power down mode
If power down mode is set, trying to read ID ends in an infinite loop
because w25_waitwritecomplete never returns as status register never
signalizes write complete. Therefore ensure the device is not in a
power down mode before trying to read from it.

This can be an issue if the board is trying to check for more NOR
memories on one SPI bus and one chip select. For example GD25 driver
returns the memory to power down state after read id is finished,
therefore board initialization is stuck in an infinite loop if it first
checks for GD25 and then fallbacks to W25.

The commit fixes the possible issue by ensuring W25 is brought back
to normal operation mode before trying to obtain the manufacturer ID.
