media: venus: fix QCOM_MDT_LOADER dependency

When build-testined with CONFIG_QCOM_MDT_LOADER=m and VIDEO_QCOM_VENUS=y,
the kernel fails to link:

x86_64-linux-ld: drivers/media/platform/qcom/venus/firmware.o: in function `venus_boot':
firmware.c:(.text+0x1e3): undefined reference to `qcom_mdt_get_size'
firmware.c:(.text+0x25a): undefined reference to `qcom_mdt_load'
firmware.c:(.text+0x272): undefined reference to `qcom_mdt_load_no_init'

The problem is the conditional 'select' statement. Change this to
make the driver built-in here regardless of CONFIG_ARCH_QCOM,
same as for the similar IRIS driver.
