media: hantro: fix post-processing NULL pointer dereference
The RK3399 variant does not have postproc_regs declared,
this can cause a NULL pointer dereference trying to decode:
[ 89.331359] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
[ 89.352804] Call trace:
[ 89.353191] hantro_postproc_disable+0x20/0xe8 [hantro_vpu]
[ 89.354056] hantro_start_prepare_run+0x58/0x68 [hantro_vpu]
[ 89.354923] hantro_h264_dec_prepare_run+0x30/0x6f0 [hantro_vpu]
[ 89.355846] rk3399_vpu_h264_dec_run+0x1c/0x14a8 [hantro_vpu]
[ 89.356748] device_run+0xa4/0xb8 [hantro_vpu]
Fix this by adding a NULL check in hantro_postproc_enable/disable.
