usbphy initializaion needs to access the power supply and has this
embedded. Refactor to a seperate power.c, since we need other accesses
in the future.

Instead of calling print_menu_entry multiple times in each case, store
the repaint state in a variable and call it once at the end to save a
few bytes of binary space.

We have the read_key function which reads a key and parses escape sequences.
Use it in the menu instead of reimplementing this manually.

When a device parameter has dots in its name, we have to use strchr instead
of strrchr, because the devicename ends at the first dot, not at the last one.

When creating a file or a directory we have to check if the parent
is actually a directory. Otherwise trying it results in a crash.

In the Kernel the mtd ioctls expect a pointer to the offset, whereas
barebox interprets the pointer itself as an offset. Since we want
to add 64bit support for file sizes a pointer may not be sufficient,
so align with the kernel and convert it to a pointer to the offset.

The dump generated by "md -w -s /dev/phy0"
suggests individual registers need to be
addressed by byte offset, not by register number.
E.g. to set the autonegotiation advertisement register
for 10Mbit only, use "mw -w -d /dev/phy0 8+2 0x0061".
The current mix of offset == register number, but
count == byte count is unintuitive.
Also, to be consistent with "md" on /dev/mem, round up
the count so "8+1" also works to access one register.
However, no attempt is made to do read-modify-write
single byte writes.

Currently the watchdog is occupied for system reset. This usage collides with
the dedicated usage of a watchdog. This patch change the behaviour of at least
i.MX23/i.MX28 where the chipset supports a simple and powerful alternative
to reset the whole SoC (including the PMIC).

We write a proper FCB, but no DBBT since it is unresolved how to keep it
in sync with Linux-based BBTs. Also, we imply searchcount = 4 and stride
= 64 (which is the default) until we can verify via ocotp.
