The Jazz machines have to use the PIT timer for dyntick and highresolution
kernels. This may break because currently just like i386 used to do MIPS
uses two separate spinlocks in the actual PIT code and the PC speaker
code. So switch to do it the same that x86 currently does PIT locking.

We can't export verify_compat_iovec when CONFIG_NET is
disabled, and consequently the Solaris compat module
should also depend upon CONFIG_NET.

When CONFIG_BUG is turned off, the standard trick of:
switch (x) {
case X:
...
case Y:
...
default:
BUG();
};
to mark impossible cases does not work because BUG() evalutes
to nothing and thus GCC just sees a fallthrough code path.
Add an explicit KERN_ERR log message and a do_exit() to trap
this case.

The I-cache disable is an errata workaround, so the solution is to
disable FIQs across the section with the I-cache disabled.

Changes:
1. The baud for spi mmc defined in board file is not used by the old
spi driver. A slower value from spi framework is used instead. In latest
bug fixing, the correct baud is use which is too high for spi MMC card.
2. SPI is enabled only after DMA is started.
3. MMC detection IRQ is set to 55.
