A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.
TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
others don't, for seemingly unrelated reasons.

SPI controllers in Intel and AMD bridges have a slightly different
restriction on how long transactions they can handle.

There are two separate restrictions to take into account:
Page Program command must not cross address boundaries defined by the
flash part's page size.
Total number of bytes for any command sent to flash part is restricted
by the SPI controller capabilities.
Consider
CONTROLLER_PAGE_LIMIT=64, page_size=256, offset=62, len=4.
This write would be split at offset 64 for no reason.
Consider
CONTROLLER_PAGE_LIMIT=40, page_size=256, offset=254, len=4.
This write would not be split at page boundary as required.
We do not really hit the second case. Nevertheless, CONTROLLER_PAGE_LIMIT
is a misnomer for the maximum payload length supported by the SPI controller
and is removed in a followup.
