AM572x SR1.1 requires different IODelay values to be used than that used
in AM572x SR2.0. These values are populated in device tree. Add
capability in omap_hsmmc driver to extract IOdelay values for different
silicon revision. The maximum frequency is also reduced when using a ES1.1.
To keep the ability to boot both revsions with the same dtb, those values
can be provided by the platform code.

>From OMAP3 SoCs (OMAP3, OMAP4, OMAP5, AM572x, AM571x), the DAT/CMD lines
reset procedure section in TRM suggests to first poll the SRD/SRC bit
until it is set to 0x1. But looks like that bit is never set to 1 and there
is an observable delay of 1sec everytime the driver tries to reset DAT/CMD.
(The same is observed in linux kernel).

Reduce the time the driver waits for the controller to set the SRC/SRD bits
to 1 so that there is no observable delay.

According to errata i802, DCRC error interrupts
(MMCHS_STAT[21] DCRC=0x1) can occur during the tuning procedure.

The DCRC interrupt, occurs when the last tuning block fails
(the last ratio tested). The delay from CRC check until the
interrupt is asserted is bigger than the delay until assertion
of the tuning end flag. Assertion of tuning end flag is what
masks the interrupts. Because of this race, an erroneous DCRC
interrupt occurs.

The suggested  workaround is to disable DCRC interrupts during
the tuning procedure which is implemented here.

"ti,dual-volt" is used in linux kernel to set the voltage capabilities.
For host controller dt nodes that doesn't have "ti,dual-volt",
it's assumed 1.8v is the io voltage. This is not always true (like in
the case of beagle-x15 where the io lines are connected to 3.3v).
Hence if "no-1-8-v" property is set, io voltage will be set to 3v.

Extend the instantiate_rng() function and the corresponding CAAM job
descriptor to instantiate all RNG state handles. This moves the RNG
instantiation code in line with the CAAM kernel driver.

Previously, only the first state handle was instantiated. The second
one was instantiated by the CAAM kernel driver. This works if the
kernel runs in secure mode, but fails in non-secure mode since the
kernel driver uses DEC0 directly instead of over the job ring
interface. Instantiating all RNG state handles in u-boot removes the
need for using DEC0 in the kernel driver, making it possible to use
the CAAM in non-secure mode.
