Allwinner USB DRD is based on the Mentor USB OTG controller, with a
different register layout and a few missing registers.

abs() takes a (signed) int as input.
Instead, it was used with unsigned 64-bit integers.
So, add and use a new helper function to calculate a difference between
two uint64_t-s.

For some unknown reason this seems to fix this function when we printf
the best variable. This isn't a delay problem as doing a printf without
it doesn't solve this problem.
This is way above my pay grade so add some printf that shouldn't be printed
in 99% of the case anyway.
Fix booting on most Allwinner boards as the mmc IP uses a NM clock.

In NECx the leading mark has length of 8T as opposed to 16T in NEC,
where T is 562.5 us. So, 4.5 ms.
Our threshold was set to 128 * 42.7 us (derived from the sampling
frequency of 3/128 MHz). So, ~5.5 ms.
The new threshold is set to AW_IR_L1_MIN. I think that's a good enough
lower bound for detecting the leading pulse.
Also, calculations of active_delay (which is activation delay) are fixed.
Previously they would be wrong if AW_IR_ACTIVE_T was anything but zero,
because the value was already bit-shifted.
Finally, I am not sure why the activation delay was divided by two when
calculating the initial pulse length. I have not found anything that
would explain or justify it. So, I removed that division.

This also adds card detection.
Note that on some boards (like the Pine64) card detection is broken due to

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Add the != 0 part to indicate that we indeed want to compare against

Not all pins in Allwinner have interrupts support so we rely
on the padconf data to add the proper caps when pin_getcaps is called.
The pin is switch to the specific "eint" function during setup_intr and
switched back to its old function in teardown_intr.
Only INTR_MAP_DATA_GPIO is supported for now.

Add a eint_bank member to the allwinner_pins structure.
On Allwinner SoCs not all pins can do interrupt.
Older SoC (A10/A13 and A20) there is a maximum number of interrupts
set to 32 and all the configuration is done in the same registers.
While on "newer" SoCs (>=A31) interrupts registers are splitted per
pin bank (i.e. all interrupts available in bank B will be configured
with a sets of registers and the one in bank G in another set).
While here set the names to all interrupts function to
pX_eintY where X is the bank name and Y the interrupt number.
To whom ever in the future look at the H5 manual and notice that the bank F
have interrupts support : This isn't true, trust me.

Each GPIO bank is powered by a different pin and so can be powered at different
voltage from different regulators.
Add a new config that now hold the pinmux data and the banks available on each
SoCs.
Since the aw_gpio driver being also the pinmux one it's attached before the PMIC
so add a config_intrhook_oneshot function that will enable the needed regulators
when the system is fully functional.

It will not enable the regulator, this is the job of either a consumer

This regulator is marked regulator-boot-on, but it will get shutdown if it's

Don't blindy say that we support both 3.3V and 1.8V.
If we have a regulator for the data lines, check that the voltage is
supported before adding the signaling caps.
If we don't have a regulator, just assume that the data lines are 3.3V
