[POWERPC] Create add_rtc() function to enable the RTC CMOS driver
In order to use the RTC CMOS driver, each architecture must register a
platform device for the RTC.
This creates a function to register the platform device based on the RTC
device node and verifies that the RTC port against the hard-coded value
in asm/mc146818rtc.h.

This cause by the initialisation of tb_to_ns_scale in time_init(), suddenly the
multiplication in sched_clock() now does something :). This patch modifies
sched_clock() to report the offset since the machine booted so the same
printk's now look like:
Add support to build the PS3 flash rom image and remove some unneeded
lmb calls.
The PS3's lv1 loader supports loading gzipped binary images from flash
rom to addr zero. The loader enters the image at addr 0x100.
In this implementation a bootwrapper overlay is use to arrange for the
kernel to be loaded to addr zero and to have a suitable bootwrapper
entry at 0x100. To construct the rom image, 0x100 bytes from offset
0x100 in the kernel is copied to the bootwrapper symbol
__system_reset_kernel. The 0x100 bytes at the bootwrapper symbol
__system_reset_overlay is then copied to offset 0x100. At runtime the
bootwrapper program copies the 0x100 bytes at __system_reset_kernel to
addr 0x100.
zImage.ps3 is a wrapped image that contains a flat device tree, an lv1
compatible entry point, and an optional initrd. otheros.bld is the gzip
compresed rom image built from zImage.ps3. otheros.bld is suitable for
programming into the PS3 boot flash memory.
