arm_adi_v5: handle faulting entry in ROM table

ARM IHI0031F "Arm Debug Interface Architecture Specification"
chapter C2.6.1 "BASE, Debug Base Address register" reports:
A debugger must handle the following situations as
non-fatal errors:
- ...
- An entry in the ROM Table points to a faulting location.
- ...
Typically, a debugger issues a warning if it encounters
one of these situations. However, Arm recommends that it
continues operating. An example of an implementation that
might cause errors of this type is a system with static
base address or ROM Table entries that enable entire
subsystems to be disabled, for example by a tie-off input,
packaging choice, fuse, or similar.

Don't halt ROM table parsing if one entry causes an error; log the
error condition and continue to next entry.
Not sure if we have to send an ABORT before continuing.
