Subject: [PATCH] rpi-update: bootloader: Only remove pieeprom*.bin and
 recovery.bin

When switching to an explicit branch only remove the pieeprom and
recovery.bin files. On Pi4 this preserves the VL805 firmware binaries.

It's unlikely that these will be updated so just preserve whatever
was there instead of implementing an update mechanism for VL805
binaries.
