It has been observed that resetting force in the detect function can
result in the PHY being powered down in response to hot-plug detect
being asserted, even when the HDMI connector is forced on.
Enabling debug messages and adding a call to dump_stack() in
dw_hdmi_phy_power_off() shows the following in dmesg:

The comment about them (also removed) says:
/* fb_rsrc and aper_rsrc aren't really used currently, but still exist
* in case we decide we need information on the BAR for BSD in the

*/
Well that was written 12 years ago in 2008. We are now in the future
and they are still superfluous. We can always add them again at a
later date if they are ever required.
