        src/sys/arch/arm/sa11x0: sa11x0_irq.S

Log Message:
irq_entry(): Do not clobber fp (= r11), in order not to confuse DDB.

Use r10 instead; no need to preserve saipic_base, previous content of
r10, throughout this function, except for the case of INTR_DEBUG.

For INTR_DEBUG, load saipic_base to scratch register every time it
becomes necessary. This is no performance penalty compared with
subsequent printf() calls.

XXX
Rewrite this function by C. There seems no particular reason to
use assembler, and no major performance regression is expected.
