terminology) to the QSPI controller.

This patch adds support to read SPI flash in Dual SPI mode, where both
MISO and MOSI lines are used for output mode (specifically Fast Read
Dual Output (0x3b) where the command is still sent normally, not Fast
Read Dual I/O (0xbb) whose additional benefit should be extremely
marginal for our use cases but which would be more complicated to
implement). This feature needs to be supported by both the flash chip
and the controller, so we add a new dual_spi flag (and a new flags field
to hold it) to the spi_flash structure and a new optional xfer_dual()
function pointer to the spi_ctrlr structure. When both are provided,
Dual SPI mode is used automatically, otherwise things work as before.
This patch only adds the dual_spi flag exemplary to all Winbond and
Gigadevice chips, other vendors need to be added as needed.

All SPI flash chip drivers currently in coreboot use the generic read
functions (spi_flash_cmd_read_fast()/_slow()) as their read callback.
The only use case for specialized read callbacks we have left is with
specialized flash controllers like Intel fast_spi (which sort of
impersonate the flash chip driver by implementing their own probe
function).
This patch unifies the behavior for all normal flash drivers by making
the read callback optional and letting them all fall back to a default
read implementation that handles normal fast/slow reading. Most of the
drivers used to install the respective callback after checking
CONFIG_SPI_FLASH_NO_FAST_READ, but some hardcoded either slow or fast
writes. I have found no indications for why this is and spot-checked
datasheets for affected vendors to make sure they all support both
commands, so I assume this is just some old inaccuracy rather than
important differences that need preserving. (Please yell if you
disagree.)
Also take the opportunity to refactor some of the common spi_flash.c
code a bit because I felt there are too many nested functions that don't
really do enough on their own, and centralizing stuff a bit should make
it easier to follow the code flow. (Some of this is in preparation for
the next patch.)

This patch changes the Gigadevice SPI flash driver to adopt the same
structure packing improvements for the hardcoded parameters of
individual chips that was implemented for Winbond last year. This cuts
the size of the hardcoded info nearly in half and should save us a few
hundred bytes in every stage.

The SPI transfer speed logging in cbfs_spi is super useful, doesn't get
in the way (just adding one line per stage, essentially) and should have
no notable overhead. Let's enable it by default for the BIOS_DEBUG log
level rather than having to recompile to get it.
Also fix an issue with building this code on MIPS due to lack of 64-bit
division primitives. (This means MIPS and arm32 board may display
incorrect results when reading more than 4MB in a single transfer, which
sounds very unlikely.)

then call the _DSM method wtih a read or write argument. The DSM
method will copy the required registers to/from the system memory
and the EC and perform the write or read action.
Responses from the EC will generate a new SCI with event code 0x79
