arm/dt: msm8974: Remove cell-index used for UART device enumeration

Currently HSUART driver uses auto increment approach for selecting id
by default. HSUART driver would increment id based on HSUART device
binding with driver. Cell-index is no longer used as id to enumerate
the device. Hence removing the cell-index entry from device tree.
