With the exception of i2c10 and i2c11 which conflict with the pins
for the third and forth MDIO controllers.
i2c0 has an ADT7490 fan controller/thermal monitor device connected. The
devicetree describes an adt74490 on i2c0, however bus that it appears on
depends on jumper settings, so it may not be present on all EVBs. It is
included to assist testing of I2C.

Requesting pinmux configuration is done at driver probe time. The LPC IP
is composed of many sub-devices, each with their own driver, and no
driver exists for the entire IP block. Avoid having each sub-device

The naming of pgtable_page_{ctor,dtor}() seems to have confused a few
people, and until recently arm64 used these erroneously/pointlessly for
other levels of page table.
To make it incredibly clear that these only apply to the PTE level, and to
align with the naming of pgtable_pmd_page_{ctor,dtor}(), let's rename them
to pgtable_pte_page_{ctor,dtor}().
These changes were generated with the following shell script:
----
git grep -lw 'pgtable_page_.tor' | while read FILE; do
sed -i '{s/pgtable_page_ctor/pgtable_pte_page_ctor/}' $FILE;
sed -i '{s/pgtable_page_dtor/pgtable_pte_page_dtor/}' $FILE;
done
----
... with the documentation re-flowed to remain under 80 columns, and
whitespace fixed up in macros to keep backslashes aligned.
There should be no functional change as a result of this patch.
