Note that .dsp_data_swap is not defined with that name in TRM (as it is
not in RK3288/RK3328), since potentially more the one bit would have to
be set for this (currently only RB_SWAP (0x2) is implemented in the VOP
driver).
To be some kind of future proof (if BG_SWAP, RG_SWAP, DELTA_SWAP or
DUMMY_SWAP ever get implemented) it should be aligned with what is
defined for RK3288/RK3328 now to automatically benefit from that
additions. And it would, since RK3288_DSP_CTRL0 BIT12, BIT13, BIT14,
BIT15, BIT16 exactly matches with RK3188_DSP_CTRL1 BIT26, BIT27, BIT28,
BIT29, BIT30.
Current implementation sets BIT13 for RK3288 and with this patch BIT27
for RK3188 to enable RB_SWAP.
