sandbox: prevent segfault in tap_alloc() ...

Tap network interface initialization in sandbox
barebox leads to segfault under Debian Buster/Sid.

The problem is that strcpy(dev, ifr.ifr_name) inside
tap_alloc() tries to alter read-only data passed
by tap_probe() and barebox receives SIGSEGV.

Nobody uses network interface name returned
by tap_alloc() so we can drop this strcpy().

net: cpsw: adopt to upstream device tree changes ...

Upstream device trees no longer have a "cpsw-phy-sel" property to find
the phy_sel register, instead they have a child device of the pinctrl
node compatible to "ti,am3352-phy-gmii-sel". Also the "rmii-clock-ext"
property is no longer global to the cpsw but instead can be selected
per slave. To adopt to these changes take the short way out for now
and find the new node by its compatible and hardcode the "rmii-clock-ext"
setting (which is set to true in am33xx-l4.dtsi and not overwritten
by any board).

This makes the cpsw driver work again. Tested on Beaglebone black
board.

pinctrl: stm32: fix error path when gpio chip is not found ...

Current error path has two issues:

- PTR_ERR is applied to a NULL pointer, so even error conditions return
  zero, which is a valid successful return.
- The return value is stored into an unsigned integer which is checked
  to be less than zero, so the error is never handled.

Fix both issues.

pstore: Only capture log messages ...

With this pstore only captures barebox log messages printed with pr_*
and dev_*, but no longer anything printed with printf and friends.

When capturing the barebox output with pstore only the log messages are
of interest, but not the ones printed with printf and certainly not
the things typed interactively on the command line. These are logged
currently because we register pstore as a barebox console. Instead, hook
into pr_puts which only outputs the barebox log messages.

Adjust psci_system_off to use ->system_off instead. This won't matter
for the existing i.MX7 PSCI implementation because it defines neither
callback, but it will for the upcoming STM32MP PSCI support.
