media: verisilicon: fix excessive stack usage
In some configurations, gcc decides not to inline the register accessor
functions, which in turn leads to lots of temporary hantro_reg structures
on the stack that cannot be eliminated because they escape into an
uninlined function:
drivers/media/platform/verisilicon/rockchip_vpu981_hw_av1_dec.c:1022:1: warning: the frame size of 1112 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Mark all of these as __always_inline so the compiler is able to completely
eliminate the temporary structures instead, which brings the stack usage
back down to just the normal local variables.
