[PATCH] mips: decrease size of au1xxx_dbdma_pm_regs[][]

[Roel Kluin <roel.kluin@gmail.com>]

Only registers [0-DDMA_CHANNEL_BASE][0-6] are used by the suspend
and resume routines.

These routines are on the bottom of the file. Only used are
registers:

au1xxx_dbdma_pm_regs[0][0-3]

and 

au1xxx_dbdma_pm_regs[1-NUM_DBDMA_CHANS][0-6]

Is my patch right, that assumes that the array can be smaller, or
should the storage and recovery of other registers be added?
