Add a C interface to set and get the bootsource instance:
int bootsource_get_instance(void);
void bootsource_set_instance(int instance);
Also export the shell variable "bootsource_instance".

This patch seperates the imx independent from the arch independent code. The
following functions and enums are renamed:
- imx_bootsource() -> bootsource_get()
- imx_set_bootsource() -> bootsource_set()
- enum imx_bootsource -> enum bootsource

__pr_printk is a define which uses a local variable 'ret'. This
means that whenever someone does a pr_*("ret: %d\n", ret);
ret will be 0.
Fix this by writing this without a local variable.

Do not write pages which only contain 0xff. UBI expects pages which
seem empty to be writable. This got lost with:

| mtd core: call driver write function with complete buffer
|
| mtd->write is supposed to loop around pages internally, no need
| to do this in mtd_write. This fixes a huge write performance drop
| with the m25p80 driver when it was converted to a mtd driver recently.
| Since mtd->writesize is 1 for this driver mtd_write ended up doing
| single byte writes on the flash.
Introduce mtd_all_ff as a global function since UBI currently has its own
implementation.

Add pread and pwrite functions.
Split read and write functions to save some space.
The functions pread and pwrite saves and sets the file
position to a given offset and restore them afterwards.
This also makes the nandtest command use these function
which is necessary to not break compilation for the nandtest
command.

The kernel nowadays has mtd_read/write and other functions. In
barebox we also have these functions, but with a different prototype,
namely they correspond to the libmtd userspace functions. Rename
these functions to libmtd_* to avoid name clashes with future mtd
updates.
