cxl/regs: Remove early capability checks in Component Register setup

Browse source

When probing the Component Registers in function cxl_probe_regs()
there are also checks for the existence of the HDM and RAS
capabilities. The checks may fail for components that do not implement
the HDM capability causing the Component Registers setup to fail too.

Remove the checks for a generalized use of cxl_probe_regs() and check
them directly before mapping the RAS or HDM capabilities. This allows
it to setup other Component Registers esp. of an RCH Downstream Port,
which will be implemented in a follow-on patch.
