before unmasking them in INTC.

Update .clang-format for LLVM 14.0, available on Ubuntu 22.04.
There is still plenty that clang-format sucks at or does wrong, so
either add some more blocks to disable it, or just put up with it.

A board may use either the LPC bus or the eSPI bus. Only include eSPI
support for boards that use it.

EC_VARIANT is only used on AVR as a parameter to avrdude.
Replace its use on ITE with 2 choices:
- CONFIG_EC_ITE_IT8587E
- CONFIG_EC_ITE_IT5570E
Replace the EC defines with a matching define for the variable.
Replace use of wildcard with list of source files to include. The `-y`
suffix is added, but has no significance since conditional compilation
has not been added yet.

Split the EC define into base and variant. Merge the 3 ATmega chips as
atmega, and the 2 ITE chips as ite.
Tested that the generated files are identical.

Add IT5570E register that controls when the down counters are updated.
Set them to update when they reach 0, instead of immediately when DCRi
is written.
Fixes keyboard color changing when changing brightness levels if not
using 0xFF for an RGB value.

Replace bare int types with stdint types. This was done with:
grep -rwl 'int' src/ | xargs sed -i 's/\<int\>/int16_t/g'
grep -rwl 'unsigned long' src/ | xargs sed -i 's/\<unsigned long\>/uint32_t/g'
grep -rwl 'unsigned char' src/ | xargs sed -i 's/\<unsigned char\>/uint8_t/g'
Then reverted for *main(), putchar(), and getchar().
The Arduino declarations for parallel_main() were also corrected to
match their definitions.
SDCC does *not* generate the same code in all instances, due to `int`
being treated different than `short int`.

Most of the code is the same between IT8587E and IT5570E.
Identical files were detected with:
diff -rs src/ec/it8587e/ src/ec/it5570e/ | egrep '^Files .+ and .+ are identical$'
Then manually moved from one variant and deleted from the other.

Per the specs, a 16-byte signature is stored at 0x40. All proprietary EC
ROMs store a space-padded 16-byte vendor string at 0x50, but it isn't
required.

By default with the large memory mode, sdcc places temp data in DSEG
(__data) and parameters in XSEG (__xdata). This causes both to be placed
on the stack instead.
Previously, the temperary variables were using up to ox69 bytes in DSEG.
After the change, temperary variables now end at 0x5D (12 bytes less).
The i2c routines were using the following XSEG bytes:
- 0x03 - 0x0b (i2c_recv - 8 bytes now on the stack)
- 0x0c - 0x14 (i2c_send - 8 bytes now on the stack)
- 0x15 - 0x1e (i2c_get - 9 bytes now on the stack)
- 0x1f - 0x2c (i2c_set - 13 bytes now on the stack)
- 0x1e2 - 0x1e5 (i2c_reset - 4 bytes now on the stack)
- 0x1e6 - ? (i2c_start - ? bytes now on the stack)
The ITE EC hardware always has the first 32KB of ram mapped, while
a second 32KB of ram is banked immediately after. By default, the
banked physical address immediately follows the fixed area in flash.

Implement configuring the keyboard controller as a parallel host device
and writing to the parallel port. This allows the EC to send log
messages over the port.
