Retire non-NEW_PCIB code and remove config option

All architectures enable NEW_PCIB in DEFAULTS (arm being the most recent
to do so in 121be555997b (arm: Set NEW_PCIB in DEFAULTS rather than a
subset of kernel configs")), so it's time we removed the legacy code
that no longer sees much testing and has a significant maintenance
burden.

arm: Set NEW_PCIB in DEFAULTS rather than a subset of kernel configs

All other architectures set NEW_PCIB in DEFAULTS, with arm being the one
remaining straggler that only sets it for GENERIC and TEGRA124.
ARMADA38X and ARMADAXP contain device pci but don't set NEW_PCIB,
however GENERIC claims to support them and as part of that NEW_PCIB
support was added to mv_pci, so these configs are most likely just
stale. Other than NOTES that just leaves ALPINE as the one kernel with
PCI support not covered by GENERIC, but al_pci is supported by arm64
which enables NEW_PCIB, and it's just a generic_pcie_fdt_driver with
some fixup code to deal with quirks so should support PCI_RES_BUS just
fine. Therefore it is believed that all in-tree kernel configs support
NEW_PCIB in reality, and so let's take a step towards removing all the
non-NEW_PCIB code by having it always-on everywhere.

This changes the default TCP Congestion Control (CC) to CUBIC.
For small, transactional exchanges (e.g. web objects <15kB), this

transfers, CUBIC allocates a slightly higher fraction of the
available bandwidth, when competing against NewReno CC.
