When read it returns all enabled interrupt sources
When written it enables interrupt sources for each bit set
So just like VIC_INT_EN_CLEAR, we don't have to read the previous value
before writing to it (VIC_INT_EN_CLEAR is write-only anyway)
Thanks to Fred Bauer for spotting

Note : SH has TIMER_FREQ defined to CPU_FREQ, so any code wanting it must include #config.h before #cpu.h

Instead use a private KERNEL_TIMER_FREQ define which is dependant on HAVE_SCROLLWHEEL
Comment that call_tick_tasks() will read the scrollwheel
Remove the unneeded volatile type qualifier from poll_scrollwheel

* Do not use |= on write only registers
* Do use it in when setting kernel tick timer

Adds read-only SD driver, largely copied from ata-sd-pp.c
Only tested on the embedded SD, on the Clip
First steps to build a Normal firmware

This way creation of scrolling thread doesn't risk crashing the system
