Some SPI flash controllers (e.g. Intel ICH) have a limit on the number of

Rather than each device having its own way to allocate a SPI flash
structure, use the new allocation function everywhere. This will make it
easier to extend the interface without breaking devices.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present it is difficult to extend the SPI flash structure since
all devices allocate it themselves, and few of them zero all fields.
Add a new function spi_flash_alloc() which can be used by SPI devices
to perform this allocation, and thus ensure that all devices can
better cope with SPI structure changes.

Analysis of the flash drivers shows that they all use 0x20 if the erase
size is 4KiB, or 0xd8 if it's larger. So with this info in hand, we can
unify all the erase functionality in one place.

I imagine much of these constants are due to copy & pasting previous
