When a PMIC is not found, this driver is unable to obtain its
'vdds_dsi_reg' regulator.  Even through its initialization function
fails, other code still calls its enable function, which fails to
check whether it has this regulator before asking for it to be enabled.

This fixes the oops, however a better fix would be to sort out the
upper layers to prevent them calling into a module which failed to
initialize.

Tomi can look into fixing this properly for v3.4:

No, it's a thing for v3.3, because you can still get this oops.

I expect _most_ of these patches will go into v3.3, and anything with
'fix' or 'oops' in especially I want to see in v3.3.
