[PATCH/RFC] ARM: shmobile: r8a7791: Fix HSUSB clock to hp_clk from mp_clk

[Yoshihiro Kaneko]

From: Kazuya Mizuguchi <kazuya.mizuguchi.ks@renesas.com>

HSUSB uses hp_clk for H/W register access.
HSUSB uses mp_clk for USB-DMAC access.
The clock is defined for H/W register access.

I plan to take this through the renesas tree unless someone objects.
In the mean time, for reference:
