PLLD is the only parent for DSIA & DSIB on Tegra124 and
Tegra132. Besides, BIT 30 in PLLD_MISC register controls
the output of DSI clock.
So this patch removes "dsia_mux" & "dsib_mux", and create
a new clock "plld_dsi" to represent the DSI clock enable
control.

Since the SDMMC controller registers are accessed via the APB,
the APB must be flushed before gating the SDMMC clocks to prevent
register accesses to the SDMMC controllers after their clocks are
gated.

vi_sensor and vi_sensor2 have a wrong hw clkid on Tegra124. Fix this by
correcting the hw clkid for Tegra124 and creating the Tegra114 vi_sensor clock
from its own data. Tegra124 was also using the wrong internal clock id.

Currently the Tegra1x4 clock init code hard-codes the mux setting
for xusb_hs_src and treats it as a fixed-factor clock. It is,
however, a mux which can be parented by either xusb_ss_src/2 or
pll_u_60M. Add the fixed-factor clock xusb_ss_div2 and put an
entry in periph_clks[] for the xusb_hs_src mux.

The parent-to-index mapping for xusb_fs_src is incorrect.
Fix it by adding a mux table.

The sdmmc clocks on Tegra114 and Tegra124 are 3-bit wide muxes with
6 parents. Add support for tegra_clk_sdmmc*_8 and switch Tegra114
and Tegra124 to use these clocks instead.

Tegra124 introduces a number of new peripheral clocks. This patch adds those
to the common peripheral clock code.

Tegra124 has a clock which consists of a mux and a fractional divider.
Add support for this.

Tegra124 has periph clocks which share the hw register. Hence locking is
required.

Introduce a new file for peripheral clocks common between several Tegra
SoCs and move Tegra114 to this new infrastructure. Also PLLP and the PLLP_OUT
clocks will be initialized here.
