Subject: [PATCH 5.4 143/344] clk: qcom: smd: Add missing bimc clock

From: Jeffrey Hugo <jeffrey.l.hugo@...il.com>

[ Upstream commit 87ec9adcca71801a44ddb311185b17df09839ab5 ]

It turns out booting the modem is dependent on a bimc vote from Linux on
msm8998.  To make the modem happy, add the bimc clock to rely on the
default vote from rpmcc.  Once we have interconnect support, bimc should
be controlled properly.
