Remove "mrvl,lpss-ssp" property from documentation because LPSS SSP type is for certain Intel platforms. I believe commita6e56c28a1("ARM: pxa: ssp: add DT bindings") added it by accident by copying all enum pxa_ssp_type types from include/linux/pxa2xx_ssp.h. Please note this was removed from arch/arm/plat-pxa/ssp.c by the commitb692cb83b1("ARM: pxa: ssp: Fix build error by removing originally incorrect DT binding").
