[SRU][O][PATCH 07/18] soc: qcom: geni-se: add GP_LENGTH/IRQ_EN_SET/IRQ_EN_CLEAR registers

From: Douglas Anderson <dianders at chromium.org>

BugLink: https://bugs.launchpad.net/bugs/2089237

For UART devices the M_GP_LENGTH is the TX word count. For other
devices this is the transaction word count.

For UART devices the S_GP_LENGTH is the RX word count.

The IRQ_EN set/clear registers allow you to set or clear bits in the
IRQ_EN register without needing a read-modify-write.
