Reading few registers at the end of the block (e.g. 0x10000) might
result in synchronous external abort, so limit the regmap to the last
readable register which allows dumping the regs for debugging.

Register map is the same as for x1e80100 and sm8750, so I am guessing
same problem.

This is not necessary on Glymur, possibly in relation to lack of Gunyah
