RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.
New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.
spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

Currently we are setting the gpio_tier1_sci in smihandler before
going to S3. But this won't work for S0iX as it happens from Linux
kernel and SMI handler is not involved in that flow. We need to
set this bit i.e. bit 15 in ACPI gpe0a register at 0x430h. The Linux
kernel before going to sleep checks what values are passed through
ASL as wake events (through _PRW), keeps those enabled only and
clears other bits in gpe0 enable registers. So we need to inform
the kernel to keep gpio_tier_sci also set as these are needed for
any wake event. This patch adds ASL code for sleep button device with
HID id PNP0C0E. We are adding _PRW method for sleep button device
with this patch.

Other platforms may provide similar support, but they do that
