Subject: [PATCH 2/5] clk: renesas: r9a09g056-cpg: Add clock and reset entries for OSTM instances

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Introduce a new fixed divider .pllcln_div16 which is sourced from PLLCLN
and add PCLK module clocks gtm_0_pclk through gtm_7_pclk for OSTM0-7. Add
corresponding reset lines GTM_0_PRESETZ through GTM_7_PRESETZ to control
the OSTM instances.
