Jiaxun Yang 191edae40a MIPS: Loongson64: Enable DMA noncoherent support 
commit edc0378eee00200a5bedf1bb9f00ad390e0d1bd4 upstream.

There are some Loongson64 systems come with broken coherent DMA
support, firmware will set a bit in boot_param and pass nocoherentio
in cmdline.

However nonconherent support was missed out when spin off Loongson-2EF
form Loongson64, and that boot_param change never made itself into
upstream.

Support DMA noncoherent properly to get those systems working.
