media: imx-pxp: Rewrite coeff expression
GCC5 cannot figure out that the expressions are constant, and that
triggers a build failure. Rewrite the expressions.
The following gcc5 error is workaround:
#define BM_PXP_CSC1_COEF0_YCBCR_MODE 0x80000000
^
BM_PXP_CSC1_COEF0_YCBCR_MODE |
^
#define BM_PXP_CSC1_COEF0_YCBCR_MODE 0x80000000
^
