Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled).

Coldfire: Partially revert buffered writes, and enable them explicitly for the LCD only. Turned out that with buffered writes enabled, reads after writes are not always serialized, which is a bad thing for I/O. Buffered writes to the LCD are safe because that's write-only. Fixes FS #7985. How come I didn't notice this earlier? :>

Coldfire targets: enable buffered writes by default. Speeds up all sorts of I/O that writes to ports: LCD update (except the functions using DMA on H300), ATA writes, .... Some timings had to be adjusted for the new configuration.

H1x0, H300: Get rid of the adc tick, and use the same concept as the iAudio ADC driver.

H1x0: Increase delay during button reads. Hopefully fixes the scroll down problem (see forum thread 11081.0).

Forget all the nonsense with C delay loops. 'volatile' on the variable makes bloated code and a volatile, blank asm block inside may or may not be optimized out. Use asm delay loops instead for Coldfire. Radio i2c driver also needs NACK after reading last tuner byte. Get the volatile off the Ondio loops (not needed here now). Maybe this is straightened out now.

Keep delay loop from being optimized away.

The ADC GPIO init code for the H100 was accidentally put in the H300 driver when moving to the target tree
