Armada CP110 UTMI supports swapping D+ and D- signals.
usb251xb.yaml already describes a suitable device-tree property for the
same purpose but as child usb controller node.

Add optional swap-dx-lanes device-tree property to armada cp110 utmi phy
with same semantics as usb251xb:
The property lists all ports that swap D+ and D-, unlisted ports are
considered correct.

While commit 255ec387 ("phy: exynos5-usbdrd: Add 26MHz ref clk
support") correctly states that CLKRSTCTRL[7:5] doesn't need to be set
on modern Exynos platforms, SSPPLLCTL[2:0] should be programmed with
the frequency of the reference clock for the USB2.0 phy instead.

I stumbled across this while adding support for the Google Tensor
gs101, but this should apply to E850 just the same.

Do so.

Using 0x82 seems odd, where everything else is just a sequence.

On E850, this macro isn't used (as a register value), only to assign
its value to the 'extrefclk' variable, which is otherwise unused on
that platform. Older platforms don't appear to support 26MHz in the
first place (since this macro was added for E850).

Furthermore, the downstream driver uses 0x82 to denote
USBPHY_REFCLK_DIFF_26MHZ (whatever that means exactly), but for all the
other values we match downstream's non-DIFF macros.

Update to avoid confusion. No functional change intended.

on / not on is just a boolean flag and is a bit misleading as currently

The timers-howto recommends using usleep_range() and friends anytime
waiting for >= ~10us is required. Doing so can help the timer subsystem
a lot to coalesce wakeups.

Additionally, fsleep() exists as a convenient wrapper so we do not have
to think about which exact sleeping function is required in which case.

Convert all udelay() calls in this driver to use fsleep() to follow the
recommendataion.

Most of the macros are ordered high -> low, but there are some
outliers.

Order them all uniformly from high to low. This will allow adding
additional register (field) definitions in a consistent way.

While at it, also remove some extra empty lines to group register bit
field definitions together with the relevant register. This makes the
registers easier to distinguish visually.
