cxl: Remove function write_timebase_ctrl_psl9() for PSL9
For PSL9 the contents of PSL_TB_CTLSTAT register have changed in PSL9
and all of the register is now readonly. Hence we don't need an sl_ops
implementation for 'write_timebase_ctrl' for to populate this register
for PSL9.
Hence this patch removes function write_timebase_ctrl_psl9() and its
references from the code.
