dt-bindings: qpnp-lcdb-regulator: Add support for PM7325B LCDB 

Add compatible string for PM7325B LCDB device. Remove pmic-revid
property as it is not used on kernel 5.4. Add pwrup-delay-ms,
qcom,bst-ps-threshold-mv and qcom,pwrup-config properties for PM7325B.
Update qcom,bst-ilim-ma, qcom,ncp-ilim-ma and qcom,ldo-ilim-ma for
PM7325B.
