iPod Classic: HW preliminary initialization for bootloader
When the bootloader starts, most of HW never has been initialized.
This patch includes all code needed to perform the preliminary
initialization on SYSCON, GPIO, i2c, and MIU.
The code is based on emCORE and OF reverse engineering, ported to
C for readability.
