media: synopsys: hdmirx: Detect broken interrupt

Downstream version of RK3588 U-Boot uses customized TF-A that remaps
HDMIRX hardware interrupt, routing it via firmware that isn't supported
by upstream driver.

Detect broken interrupt and print a clarifying error message about a need
to use open-source TF-A with this driver.
