drm/rockchip: dw_hdcp2: always support unlocked_ioctl() file operation

Browse Source 
In both the Android SDK and Linux SDK, when compiling for a 64-bit
system, the CONFIG_COMPAT macro is enabled, but the unlocked_ioctl call
is not compiled. The hdcp2_tx_rx service compiled on Android is 32-bit,
corresponding to a 64-bit kernel. Therefore, ioctl calls go through
compat_ioctl without any issues. However, services and kernels built
with the NVR SDK and Linux SDK are consistent at 64 bits. This causes
ioctl calls to go through unlocked_ioctl, leading to exceptions.
