mailbox: use uncached address to write sw regs 

mailbox_sw_regs_write is used by dai to update llp node. In multi-core
test, the updated llp node is invisable to other cores although
dcache_writeback_region is used on both cavs & ace platforms. Now use
uncached address to write memory directly which is aligned with other
mailbox access functions.

Validated on cavs & ace platforms.
