In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.
This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.
The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

If the host command handler callback function returns an int, it's easy
to accidentally mix up the enum ec_error_list and enum ec_status types.
The host commands always expect an enum ec_status type, so we change the
return value to be of that explicit type. Compilation will then fail if
you accidentally try to return an enum ec_error_list value.
Ran the following commands and then manually fixed up a few remaining
instances that were not caught:
git grep --name-only 'static int .*(struct host_cmd_handler_args \*args)' |\
xargs sed -i 's#static int \(.*\)(struct host_cmd_handler_args \*args)#\
static enum ec_status \1(struct host_cmd_handler_args \*args)##'
git grep --name-only 'int .*(struct host_cmd_handler_args \*args)' |\
xargs sed -i 's#int \(.*\)(struct host_cmd_handler_args \*args)#\
enum ec_status \1(struct host_cmd_handler_args \*args)##'

The CTR was set to 1 less than the max PWM value, so when the DCR
is set to max PWM value, duty goes to zero. The bug is fixed by
setting CTR to PWM max vlaue.

The current PWM interface allows for a pwm duty setting ranging from
0 to 100, resulting in a very coarse adjustment. To alleviate the
problem, the interface now allows for a pwm duty setting in the range
of 0 to 65535.

Since pretty much always, we've declared console commands to take
a "longhelp" argument with detailed explanations of what the
command does. But since almost as long, we've never actually used
that argument for anything - we just silently throw it away in
the macro. There's only one command (usbchargemode) that even
thinks it defines that argument.
We're never going to use this, let's just get rid of it.

EC_CMD_PWM_SET_DUTY / EC_CMD_PWM_GET_DUTY were recently added and are
not yet in use. Future-proof these commands by taking a 16-bit duty
cycle parameter and converting it between the [0-100] percent used by
internal EC functions.

Add generic PWM host commands for setting + getting duty cycle. PWMs can
be controlled through index (board-specific meaning) or by type

added as needed).

The common/ subdir was getting cluttered. Move drivers for external
components to a new driver/ tree, and move what used to be called
chipset_*.c to a new power/ directory.
This does not move/rename header files or CONFIG options. That will
be done in subsequent steps, since moving and modifying .c files in
the same CL is harder to review.
