It is tedious to define both mask and bit-shift. <linux/bitfield.h>
provides a convenient way to get access to register fields with a
single shifted mask.

Synopsys HSDK clock controller generates and supplies clocks to various
controllers and peripherals within the SoC.
Each clock has assigned identifier and client device tree nodes can use
this identifier to specify the clock which they consume. All available
clocks are defined as preprocessor macros in the
dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device
tree sources.

dcache_exists, icache_exists, slc_exists and ioc_exists global
variables in "arch/arc/lib/cache.c" remain uninitialized if
SoC doesn't have corresponding HW.
This happens because we use the next constructions for their
definition and initialization:
-------------------------->>---------------------
int ioc_exists __section(".data");
if (/* condition */)
ioc_exists = 1;
-------------------------->>---------------------
That's quite a non-trivial issue as one may think of it.
The point is we intentionally put those variables in ".data" section
so they might survive relocation (remember we initilaize them very early
before relocation and continue to use after reloaction). While being
non-initialized and not explicitly put in .data section they would end-up
in ".bss" section which by definition is filled with zeroes.
But since we place those variables in .data section we need to care
about their proper initialization ourselves.
Also while at it we change their type to "bool" as more appropriate.

DW SDIO controller has external CIU clock divider controlled via
register in the SDIO IP. Due to its unexpected default value
(we expected it to divide by 1 but in reality it divides by 8)
SDIO IP uses wrong CIU clock (it should be 100000000Hz but actual
is 12500000Hz) and works unstable (see STAR 9001204800).
So increase SDIO CIU frequency from actual 12500000Hz to 50000000Hz
by switching from the default divisor value (div-by-8) to the
minimum possible value of the divisor (div-by-2) in HSDK platform
code.
