checkpatch: Add warnings for using strn(cat|cpy)

strn(cat|cpy) has a bad habit of not nul-terminating the destination,
resulting in constructions like

strncpy(foo, bar, sizeof(foo) - 1);
foo[sizeof(foo) - 1] = '\0';

However, it is very easy to forget about this behavior and accidentally
leave a string unterminated. This has shown up in some recent coverity
scans [1, 2] (including code recently touched by yours truly).

Fortunately, the guys at OpenBSD came up with strl(cat|cpy), which always
nul-terminate strings. These functions are already in U-Boot, so we should
encourage new code to use them instead of strn(cat|cpy).

video: SIMPLE_PANEL depends on DM_GPIO

SIMPLE_PANEL currently only depends on PANEL && BACKLIGHT, but the code
makes references to dm_gpio_set_value and gpio_request_by_name.  These
are defined in drivers/gpio/gpio-uclass.c, so a dependency on DM_GPIO
corrects these link errors:

aarch64-linux-gnu-ld.bfd: drivers/built-in.o: in function `simple_panel_set_backlight':
/home/kameliya/u-boot/drivers/video/simple_panel.c:42: undefined reference to `dm_gpio_set_value'

This issue is only exposed if you have a board which enables
CONFIG_DM_VIDEO without CONFIG_DM_GPIO; so far, none do, but soon a QEMU

pwm: Add a driver for Chrome OS EC PWM

This PWM is used in rk3399-gru-bob and rk3399-gru-kevin to control
the display brightness. We can only change the duty cycle, so on
set_config() we just try to match the duty cycle that dividing duty_ns
by period_ns gives us. To disable, we set the duty cycle to zero while
keeping the old value for when we want to re-enable it.

The cros_ec_set_pwm_duty() function is taken from Depthcharge's
cros_ec_set_bl_pwm_duty() but modified to use the generic pwm type.
The driver itself is very loosely based on rk_pwm.c for the general pwm
driver structure.

The devicetree binding file is from Linux, before it was converted to
YAML at 5df5a577a6b4 ("dt-bindings: pwm: Convert google,cros-ec-pwm.txt
