This commit adds/modifies `riscv,isa` strings using the following rules:
* the ISA string is lowercase
* multi-letter extensions are preceded with the underscore mark
* if an extension is implied by another one, it is not specified - e.g. the
D extension implies the F extension, so writing `rv32ifd` is redundant

Sometimes, channel C may write wrong register to the target device.
This issue occurs when FIFO2 is enabled on channel C. The problem
arises because FIFO2 is shared between channel B and channel C.
FIFO2 will be disabled when data access is completed, at which point
FIFO2 is set to the default configuration for channel B.
The byte counter of FIFO2 may be affected by channel B. There is a
chance that channel C may encounter wrong register being written due
to the FIFO2 byte counter wrong write after channel B's write operation.
The current workaround is that channel C cannot use FIFO mode.

Executing code out of RAM on IT8xxx2 requires that the relevant
addresses be mapped onto the CPU's instruction memory bus, referred to
by ITE documentation as Instruction Local Memory (ILM). ILM mappings
configure blocks of RAM to be used for accesses to chosen addresses when
performing instruction fetch, instead of the memory that would normally
be accessed at that address.
ILM must be used for some chip features (particularly Flash
self-programming, to execute from RAM while writing to Flash), and has
historically been configured in the Flash driver. The RAM for that was
hard-coded as a single 4k block in the linker script. Configuring ILM
in the flash driver is confusing because it is used by other SoC code as
well, currently in code that cannot depend on the Flash being functional
or in hand-selected functions that seem performance-critical.
This change moves ILM configuration to a new driver and dynamically
allocates RAM to ILM in the linker script, allowing software use of the
entire 64k RAM depending on configuration. This makes ILM configuration
more discoverable and makes it much easier to correctly support the
CODE_DATA_RELOCATION feature on this SoC.

GD32 FMC v2: its flash memory has 2 banks. Page size equal within the
same bank but different between banks. Flash size can be up to 3072KB.
FMC v2 has two registers to control bank0 and bank1 separately.
GD32 FMC v3: its flash memory has 2 banks, use sector size as the
minimum operating unit, the sector size is not equal.

This patch adds a clock control driver for GD32 platforms. It is
important to note that the driver is only able to handle peripheral
clocks, but not "system clocks" (e.g. PLL settings, SYS_CK, etc.). On
some similar platforms (STM32) this task is embedded in the same clock
driver, performed at init time but with no options to do any
manipulation at runtime via the API calls. The clock control API as-is
is really orthogonal to "system clocks", and it is arguably a bad idea
to embed system clock init code in a clock control driver. It can be
done at SoC level still using Devicetree as a source of hardware
description/initial configuration.

Adding I2C FIFO mode can reduce the time between each byte to
improve the I2C bus clock stretching during I2C transaction.
The I2C master supports two 32-bytes FIFOs, channel A and C
are supported now.
I2C FIFO mode of it8xxx2 can support I2C APIs including:
i2c_write(), i2c_read(), i2c_burst_read.
Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
0.52ms(2.4ms->1.88ms) compared to the original pio mode when the
frequency is 100KHz.
3. It is normal to read sensor data through I2C on Nereid's platform.
