dwc3: add ACPI attachment

Split the current FDT-only implementation up into an FDT and an
ACPI part reusing and sharing as much code as possible (thanks mw!).

This makes the Synopsis XHCI root hubs attach correctly on SolidRun's
HoenyComb instead of just the generic XHCI root and this means we
are also doing proper chip setup and applying the quirk needed there [1].

There is one problem with ACPI attachment in that it uses the generic
XHCI PNP ID. So we need to do extra checks in order to not claim
all xhci, which means we check for a known quirk to be present
in acpi_probe. Long term this isn't scaling and this was discussed
in SolidRun's Discord Channel in 2021 with the intend that "jnettlet"
will take this to a steering committee. Since then ACPI has kind-of
become a technology non grata (due to not getting changes into Linux
timely) so it is unclear if this will ever happen. If there will be
further hardware with dwc3/ACPI we should go and make sure this problem
gets solved.

dwc3: fix from not working

During the review of 09cdf4878c621be4cd229fa88cdccdcdc8c101f7 we
switched from cached registers to reading them as needed.
One read of the two reads was moved after the softreset got triggered
and as a result returned 0 rather than the proper register value.
Moving the read before the softreset gets initiated seems to make
things work again and xhci.c no longer complains about
"Controller does not support 4K page size.".

dwc3: improve debugging

Rather than hiding behind #if 0, hide the debugging behind DWC3_DEBUG
so it can be turned on with a single define. Require bootverbose
to print anything so we can still avoid spamming the console if DWC3_DEBUG
is on.
Harmonize the format string in snsp_dwc3_dump_regs() to always print the
full register and also print the XHCI quirks.
Call snsp_dwc3_dump_regs() twice, before and after generic XHCI attachment
and initialisation as this may have an effect on the confirgumation state.
