ARM: shmobile: Introduce shmobile_clk_workaround()

Introduce a new clock workaround function used by DT reference
code on the mach-shmobile subarchitecture. The new function
shmobile_clk_workaround() is used to configure clkdev to
allow DT and platform devices to coexist. It is possible for
the DT reference board code to also request enabling of the clock
in case the driver does not implement clock control.

ARM: shmobile: r8a7790: Rename VSP1_(SY|RT) clocks to VSP1_(S|R)

The r8a7790 has four VSP1 instances, two of them being named VSPS (which
stands for "VSP Standard") and VSPR (which stands for "VSP for
Resizing"). The clock section in the SoC datasheet misunderstood the
abbreviations as meaning VSP System and VSP Realtime, and named the
corresponding clocks VSP1(SY) and VSP1(RT). This mistake has been
carried over to the kernel code.

Fix this by renaming the VSP1_SY and VSP1_RT clocks to VSP1_S and VSP1_R.

ARM: shmobile: koelsch-reference: Work around core clock issues

Due to issues with runtime PM clock management, clocks not explicitly
managed by their drivers may not be enabled at all, or be inadvertently
disabled by the clk_disable_unused() late initcall.

Until this is fixed, add a temporary workaround, calling
shmobile_clk_workaround() with enable == true.

For now this enables the clocks for: ether, i2c2, msiof0, qspi_mod, and
thermal. More clocks can be added if needed.

 2) add new style clock method in driver
 3) remove old tyle clock from platform
