[PATCH v2 2/5] ARM: OMAP2+: DRA7: Add hwmod entries for PWMSS

[Vignesh R]

Add hwmod entries for the PWMSS on DRA7.

Set l4_root_clk_div as the main_clk of PWMSS. It is fixed-factored clock
equal to L4PER2_L3_GICLK/2(l3_iclk_div/2).
As per AM57x TRM SPRUHZ6[1], October 2014, Section 29.1.3 Table 29-4,
clock source to PWMSS is L4PER2_L3_GICLK. But it is actually
L4PER2_L3_GICLK/2. The TRM does not show the division by 2.
