[RFT PATCH] clk: qcom: dispcc-x1e80100: Fix (possibly) dumping regmap

[Krzysztof Kozlowski]

Reading few registers at the end of the block (e.g. 0x10000, 0x10004)
might result in synchronous external abort, so limit the regmap to the
last readable register which allows dumping the regs for debugging.

Not really tested, just idea based on sm8750 and datasheet/manual.
