By rearranging the functions in the semihosting code we can
avoid forward-declaration of the internal static functions.
This puts the stuff in a logical order: read/open/close/len
and then higher-order functions follow at the end.

There is currently a regression when using newer ARM64 compilers
for semihosting: the way long types are inferred from context
is no longer the same.
The semihosting runtime uses long and size_t, so use this
explicitly in the semihosting code and interface, and voila:
the code now works again.

The semihosting code exposes internal file handle handling
functions to read(), open(), close() and get the length of
a certain file handle.
However the code using it is only interested in either
reading and entire named file into memory or getting the
file length of a file referred by name. No file handles
are used.
Thus make the file handle code internal to this file by
removing these functions from the semihosting header file
and staticize them.
This gives us some freedom to rearrange the semihosting
code without affecting the external interface.

Implement an API that can be used by drivers to allocate memory from a
pool that is mapped uncached. This is useful if drivers would otherwise
need to do extensive cache maintenance (or explicitly maintaining the
cache isn't safe).
The API is protected using the new CONFIG_SYS_NONCACHED_MEMORY setting.
Boards can set this to the size to be used for the non-cached area. The
area will typically be right below the malloc() area, but architectures
should take care of aligning the beginning and end of the area to honor
any mapping restrictions. Architectures must also ensure that mappings
established for this area do not overlap with the malloc() area (which
should remain cached for improved performance).
While the API is currently only implemented for ARM v7, it should be
generic enough to allow other architectures to implement it as well.

Fortunately, this problem was solved by commit 70879a9256 (flash:

Eventually, this information can be used for tasks such as:
- Allowing/preventing USB device mode; some models have a USB device on-
board so only host mode makes sense. Others connect the SoC directly
to the USB connector, so device-mode might make sense.
- The on-board USB hub/Ethernet requires different GPIOs to enable it,
although luckily the default appears to be fine so far.
- The compute module contains an on-board eMMC device, so we could store
the environment there. Other models use an SD card and so don't support
saving the environment (unless we store it in a file on the FAT boot
partition...)

The infomation of module control register for R-Car ARM SoC (r8a7790, r8a7791,
r8a7793 and r8a7794) are almost the same, they can be combined into one
structure. This provides structure that summarizes infomation of module control
register and default register values.
And this structure is the module control use of the kernel at boot time.

This addes macro for set and clear bit control for module control register.
This is used when user want to disable the function of the devices
corresponding to register.

Control macro of mstp is common in R-Car ARM SoC (r8a7790, r8a7791,
r8a7793 and r8a7794). This moves these to arch-rmobile/rcar-mstp.h

Module control registers of R-Car ARM SoC (r8a7790, r8a7791, r8a7793 and
r8a7794) are same address. This moves these to header file of SoC.
