GCC 4.3.3 and 4.4.1 happily moves the dword load instruction out of the
loop in orion_nand_read_buf. This patch makes the instruction volatile
to avoid the issue. I've discussed this at gcc-help, refer to the thread
at
http://gcc.gnu.org/ml/gcc-help/2009-08/msg00187.html
The early clobber is added to avoid the destination registers and the
source register overlapping.

This is not 8 times faster than byte access, but still around 60% faster.

This patch performs the equivalent include directory shuffle for
plat-orion, and fixes up all users.

This just leaves include/asm-arm/plat-* to deal with.

Some SoCs need a different chip_delay value.

Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is
prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MTD NAND
platform drivers, to re-enable auto loading.
NOTE: at91_nand for some reason disallows modular builds. I'm assuming that's
just an oversight that will be fixed.
