[PATCH] clk: qcom: Enumerate clocks and reset needed to boot the 8998 modem

[Jeffrey Hugo <jeffrey.l.hugo@gmail.com>]

We need to control five additional clocks and a reset inorder to boot the
modem on msm8998.  If we can boot the modem, we have a place to run the
wlan firmware and get wifi up and running.
