drm/i915/guc: Correct capture of EIR register on hang
The EIR register (0x20B0) was being included in the engine class list
for render and compute as the absolute register address. However, it
is actually a ring register available on all engines at an offset of
(base) + 0xB0. As it was included as an RCS engine but with the
absolute address, GuC was adding on another 0x2000 and coming out at
an invalid location. Thus it would reject the register and complain
about only managing a partial capture.
So update the list to use the RING_EIR version of the register and
include it for all engines.
