arm64: dts: qcom: sm8550: fix LPASS pinctrl slew base address
The second LPASS pin controller IO address is supposed to be the MCC range which contains the slew rate registers. The Linux driver then accesses slew rate register with hard-coded offset (0xa000). However the DTS contained the address of slew rate register as the second IO address, thus any reads were effectively pass the memory space and lead to "Internal error: synchronous external aborts" when applying pin configuration.
