sandbox: also restore terminal settings when killed by SIGINT
Hitting Ctrl-C is a documented way to exit the sandbox, but it is not
actually equivalent to the reset command. The latter, since it follows
normal process exit, takes care to reset terminal settings and
restoring the O_NONBLOCK behaviour of stdin (and, in a terminal, that
is usually the same file description as stdout and stderr, i.e. some
/dev/pts/NN).
Failure to restore (remove) O_NONBLOCK from stdout/stderr can cause
very surprising and hard to debug problems back in the terminal. For
example, I had "make -j8" consistently failing without much
information about just exactly what went wrong, but sometimes I did
get a "echo: write error". I was at first afraid my disk was getting
bad, but then a simple "dmesg" _also_ failed with write error - so it
was writing to the terminal that was buggered. And both "make -j8" and
dmesg in another terminal window worked just fine.
So install a SIGINT handler so that if the chosen terminal
mode (cooked or raw-with-sigs) means Ctrl-C sends a SIGINT, we will
still call os_fd_restore(), then reraise the signal and die as usual
from SIGINT.

x86: apl: Move p2sb ofdata reading to the correct method
With P2SB the initial BAR (base-address register) is set up by TPL and
this is used unchanged right through U-Boot.
At present the reading of this address is split between the ofdata() and
probe() methods. There are a few problems that are unique to the p2sb.
One is that its children need to call pcr_read32(), etc. which needs to
have the p2sb address correct. Also some of its children are pinctrl
devices and pinctrl is used when any device is probed. So p2sb really
needs to get its base address set up in ofdata_to_platdata(), before it is
probed.
Another point is that reading the p2sb BAR will not work if the p2sb is
hidden. The FSP-S seems to hide it, presumably to avoid confusing PCI
enumeration.
Reading ofdata in ofdata_to_platdata() is the correct place anyway, so
this is easy to fix.
Move the code into one place and use the early-regs property in all cases
for simplicity and to avoid needing to probe any PCI devices just to read
the BAR.
