Subject: [PATCH] clk: qcom: Update the force mem core bit for GPU clocks

From: Taniya Das <quic_tdas@...cinc.com>

There are few GPU clocks which are powering up the memories
and thus enable the FORCE_MEM_PERIPH always for these clocks
to force the periph_on signal to remain active during halt
state of the clock.

Fixes: 3e0f01d6c7e7 ("clk: qcom: Add graphics clock controller driver for SC7280")
