Christian Marangi c592e3ea02 mips: bmips: BCM6358: make sure CBR is correctly set 
[ Upstream commit ce5cdd3b05216b704a704f466fb4c2dff3778caf ]

It was discovered that some device have CBR address set to 0 causing
kernel panic when arch_sync_dma_for_cpu_all is called.

This was notice in situation where the system is booted from TP1 and
BMIPS_GET_CBR() returns 0 instead of a valid address and
!!(read_c0_brcm_cmt_local() & (1 << 31)); not failing.

The current check whether RAC flush should be disabled or not are not
enough hence lets check if CBR is a valid address or not.

Fixes: ab327f8acdf8 ("mips: bmips: BCM6358: disable RAC flush for TP1")
