imx8m has the only implementation of `reset_cpu` which does not ignore
the addr parameter and instead gives it some meaning as the base address
of watchdog registers. This breaks convention with the rest of U-Boot
where the parameter is ignored and callers are passing in 0.
Fixes: d2041725e8 ("imx8m: restrict reset_cpu")

Use the `do_reset` implementation of `arch/arm/lib/reset.c` in SPL
instead. It is very close to what is done here, anyway, and plays
more nicely with the rest of U-Boot than adding a custom `do_reset`
implementation into board files.
`do_reset` from `arch/arm/lib/reset.c` calls `reset_cpu` with 0 as the
addr parameter while the boards are passing WDOG1_BASE_ADDR. This is
ok because the `reset_cpu` implementation uses WDOG1_BASE_ADDR by
default if 0 is passed in.

When doing reset_cpu, in normal case the WDOG_B outputs immediately
after we clean WDA bit. But on mscale, the WDOG_B may be later than
internal reset, and cause PMIC not reset. As we enabled the SD3.0
support, the PMIC must be reset to reset SD card.
Change the reset_cpu to enable the WDOG_B for timeout as well, and set
WDOG timeout to 1s.

turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:
"GPL" Module is licensed under GPL version 2. This
does not express any distinction between
GPL-2.0-only or GPL-2.0-or-later. The exact
license information can only be determined
via the license information in the
corresponding source files.
And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.
