iPod Classic: enable IRAM1 in bootloader

Browse source 
7442742 ("iPod Classic: disable IRAM1") was causing subsequent ipod6g
bootloader builds to result in a completely black screen upon
installation, with recovery only possible with a reflash through DFU
mode.

IRAM1 is re-enabled for bootloader only.
