Replace unbounded strcpy()/sprintf() calls with snprintf() and
check the return value against remaining buffer capacity at each
append step. The previous size guard did not account for
subsequent dpi suffix, remaining bootargs tail, and bootdev
token appends, allowing overflow when those later writes exceed
the remaining space.

We don't need an API specially for non-watchdog since md5_wd supports
it by disabling CONFIG_HW_WATCHDOG and CONFIG_WATCHDOG.
Set 0x10000 as default chunk size for MD5.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Now that we have time conversion defines from in time.h there is no need
for each driver to define their own version.

The way that the timer support is currently done for exynos/nexell
platforms relies on the legacy PWM infrastructure, and that needs to be
updated. However, we really cannot safely undef CONFIG_DM_PWM to build
the timer.c file without warnings. For now, rename the relevant legacy
functions to be prefixed with s5p_ and add prototypes to the arch pwm.h
files.

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM
namespace do not easily transition to Kconfig. In many cases they likely
should come from the device tree instead. Move these out of CONFIG
namespace and in to CFG namespace.

We rename the S5P specific "CONFIG_PWM" to CONFIG_PWM_S5P and move it to
Kconfig.  Given the usage of CONFIG_PWM_NX, we have that select this new
symbol.
