Use clkidx when registering MSTP clocks instead of loop counter
since the value is then used to access the specific clock index bit
in the mstp register.
The issue was introduced by the following commit:
f94859c215 "clk: shmobile: Add MSTP clock support"

Device tree clock binding document for EMMA Mobile EV2 SMU,
And Common clock framework based implementation of it.
Following nodes are defined to describe clock tree.
- renesas,emev2-smu
- renesas,emev2-smu-clkdiv
- renesas,emev2-smu-gclk
These bindings are designed manually based on
19UH0037EJ1000_SMU : System Management Unit User's Manual
So far, reparent is not implemented, and is fixed to index #0.
Clock tree description is not included, and should be provided
by device-tree.

MSTP clocks are gate clocks controlled through a register that handles
up to 32 clocks. The register is often sparsely populated.
Those clocks are found on Renesas ARM SoCs.

DIV6 clocks are divider gate clocks controlled through a single
register. The divider is expressed on 6 bits, hence the name, and can
take values from 1/1 to 1/64.
Those clocks are found on Renesas ARM SoCs.

The R-Car Gen2 SoCs (R8A7790 and R8A7791) have several clocks that are
too custom to be supported in a generic driver. Those clocks can be
divided in two categories:
- Fixed rate clocks with multiplier and divisor set according to boot
mode configuration
- Custom divider clocks with SoC-specific divider values
This driver supports both.
