Improve description of mx25l12833f.
Add note about mx25l12833f using the same JEDEC ID as mx25l12805d.

Improve description.
Rename _nor_send_cmd() to spi_nor_send_cmd_internal()
Remove MX25L12833F specific changes.
Add reading SFDP to all Macronix chips.
Add support of reading OTP parameters from device tree.
Reorgenize patches to 2 SPI-NOR patches and 2 Macronix patches
