ARM: dts: msm: add PM8998 LDO 1 active-only regulator device for sdm845

Add an active-only rpmh-regulator device for the PM8998 LDO 1
RPMh resource so that consumers can issue LDO 1 requests which
only apply when the application processor is awake.  Also add
a sleep-only rpmh-regulator device for LDO 1 in order to capture
the default sleep request: off in low power mode.  This ensures
that the LDO is disabled during sleep in the case that no
consumers utilize the active + sleep regulator device.
