This is an MFD with regulators, an RTC and a watchdog, among other
things. This adds the necessary infrastructure for specific children to
be added.
Note that the PMIC can also be attached via SPI, not just I2C, and so
the interface is abstracted. No SPI implementation is added, however.

Netgraph has two main types of message items:
- NGQF_DATA items are used for data processing. This is a hot path that
should be called from a NET_EPOCH context.
- NGQF_MESG items are used for node configuration. There are many places
in netgraph(4) where processing the NGQF_MESG item can call sections of code
that are forbidden in the NET_EPOCH context.
All item types can be queued and then processed using ngthread().
But ngthread() is unconditionally enter in the NET_EPOCH section for all types.
This causes panic/deadlocks when processing NGQF_MESG elements.

This changes the default TCP Congestion Control (CC) to CUBIC.
For small, transactional exchanges (e.g. web objects <15kB), this
will not have a material effect. However, for long duration data
transfers, CUBIC allocates a slightly higher fraction of the
available bandwidth, when competing against NewReno CC.

Ensure that we always pass sane limits for the high and low watermark
values.
This is especially important if users do something silly, like set the
state limit to 1. In that case we wound up calculating 0/0 as a limit,
which gets rejected by the kernel.
While here also shift the calculation to use uint64_t, so we don't end
up with overflows (and subsequently higher low than high values) with
very large state limits.

When attempting to promote 4KB user-space mappings to a 2MB user-space
mapping, the address of the struct vm_page representing the page table
page that contains the 4KB mappings is already known to the caller.
Pass that address to the promotion function rather than making the
promotion function recompute it, which on arm64 entails iteration over
the vm_phys_segs array by PHYS_TO_VM_PAGE(). And, while I'm here,
eliminate unnecessary arithmetic from the calculation of the first PTE's
address on arm64.

kern.cam.da.default_softtimeout currently does nothing. It sets a value
in the CCB that SIMs could look at, only none do. Leave it undocumented
until it actually does something. It was introduced to allow a 'soft
recovery' to be started when things were taking too long in the SIM by
not scheduling new I/O, or other measures the SIM knew would help when
it seemed like things were getting 'backed up'. No SIM in the FreeBSD
tree implements this and scsi_da doesn't use it other than to pass it
down, so best remove it from the documentation until it does something.
