[PATCH 2/2] ARM: dts: am43xx-clocks: Fix ehrpwm tbclk data on am43xx

ehrpwm tbclk is wrongly modelled as deriving from dpll_per_m2_ck.
The TRM says tbclk is derived from SYSCLKOUT. SYSCLKOUT nothing but the
functional clock of pwmss (l4ls_gclk).
Fix this by changing source of ehrpwmx_tbclk to l4ls_gclk.

Fixes: 4da1c67719f61 ("add tbclk data for ehrpwm")
