As part of removing cpu_...() from the OMAP I2C driver, we need to
convert the CPU tests into functionality flags that are set by
hwmod class in the same way the IP revision is.
More flags are needed than will fit in the existing u8 flags
member of omap_i2c_dev_attr.
These flags can refer to options inside the IP block but they are
most needed for information about cpu implementation specific
options that are not part of the IP block itself. For example,
how the CPU data bus is wired to the IP block databus differs
between OMAP cpus and affects how you must shift the address in
the IP block, but is not a feature of the IP block itself.

Replace current usage of _find_by_pdev() with to_omap_device() since

The naming convention used by commit 7538e3db6e015e890825fbd9f86599b
(PM: Add support for device power domains), which introduced the
struct dev_power_domain type for representing device power domains,
evidently confuses some developers who tend to think that objects
of this type must correspond to "power domains" as defined by
hardware, which is not the case. Namely, at the kernel level, a
struct dev_power_domain object can represent arbitrary set of devices
that are mutually dependent power management-wise and need not belong
to one hardware power domain. To avoid that confusion, rename struct
dev_power_domain to struct dev_pm_domain and rename the related
pointers in struct device and struct pm_clk_notifier_block from
pwr_domain to pm_domain.

Most of the ASM sleep code (in arch/arm/mach-omap2/sleep34xx.S)
is copied to internal SRAM at boot and after wake-up from CORE OFF
mode. However only a small part of the code really needs to run from
internal SRAM.
This fix lets most of the ASM idle code run from the DDR in order to
minimize the SRAM usage and the overhead in the code copy.
The only pieces of code that are mandatory in SRAM are:
- the i443 erratum WA,
- the i581 erratum WA,
- the security extension code.
SRAM usage:
- original code:
. 560 bytes for omap3_sram_configure_core_dpll (used by DVFS),
. 852 bytes for omap_sram_idle (used by suspend/resume in RETention),
. 124 bytes for es3_sdrc_fix (used by suspend/resume in OFF mode on ES3.x),
. 108 bytes for save_secure_ram_context (used on HS parts only).
With this fix the usage for suspend/resume in RETention goes down 288
bytes, so the gain in SRAM usage for suspend/resume is 564 bytes.
Also fixed the SRAM initialization sequence to avoid an unnecessary
copy to SRAM at boot time and for readability.
Tested on Beagleboard (ES2.x) in idle with full RET and OFF modes.

3630/Zoom3

omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and
'dma_channel' are never referenced by the NAND driver, yet various
board files are initializing those fields. This is both incorrect and
confusing, so remove them. This allows to get rid of a global
variable in gpmc-nand.c.
This also corrects an issue where some boards are trying to pass NAND
16bit flag through .options, but the driver is using .devsize instead
and ignoring .options.
Finally, .dev_ready is treated as a flag by the driver, so make it bool
instead of a function pointer.
