drivers/mtd: replace checks by assert in mtd_dev_get
...
Assertions are used instead of returning a NULL pointer to detect errors in the MTD definition and access in the case that the return value is not evaluated.

drivers/mtd: fix the order in the MTD pointer XFA
...
The commit fixes the order of entries in the MTD pointer XFA `mtd_dev_xfa` according to their index by using the index as the priority in the XFA.

mtd: rename mtd_write_page() -> mtd_write_page_raw()
...
The function will not abstract away the behavior of the underlying media
(e.g. whether only 1 -> 0 writes are possible without erase), thus rename it.

mtd: add page addressed operations
...
Currently read(), write() and erase() all use 32 bit addressing.
This is a problem when writing to media > 4 GiB, e.g. SD cards.
The current implementation would wrap around after 4 GiB and corrupt data.
To avoid this, add functions to the MTD subsystem that allow for page-wise
addressing. This is how most of the underling storage drivers and the
file-systems above work anyway.
In the future we should then deprecate the 32-bit functions if all drivers
are converted.

mtd: Change API to return 0 on success
...
Returning the number of bytes written/read could return a negative integer
because a uint32_t is expected for the length in read()/write() operations.
