Subject: [PATCH v1 00/14] mtd: spi-nor: move vendor specific code into vendor modules

It turns out that most of the special status register handling is
specific for a particular vendor. I.e. Xilinx has some different
opcodes for the status register read, Micron has an additional FSR
register and Spansion has these flags integrated into the SR.

Create a callback to ready() where a flash chip can register its
own function. This will let us move all the vendor specific stuff
out of the core into the vendor modules.

Please note that this is only compile-time tested.

For sake of consistency and better readability of the code flow,
I also converted the setup() callback to be optional.
