docs: Remove documentation for "custom" command blocks

Browse Source 
It should no longer be necessary to configure "custom" commands during
mcu setup.  The ad5206 and static_digital_output config sections
should provide similar functionality.

commands, these commands run as soon as they are received and they do
not require any particular setup.
These commands are most useful in the "custom" block of the "mcu"
section of the printer configuration file. This feature is typically
used to configure the initial settings of LEDs, to configure
micro-stepping pins, to configure a digipot, etc.
Several of these commands will take a "pin=%u" parameter. The
low-level micro-controller software uses integer encodings of the
hardware pin numbers, but to make things more readable the host will
translate human readable pin names (eg, "PA3") to their equivalent
integer encodings. By convention, any parameter named "pin" or that
has a "_pin" suffix will use pin name translation by the
host. Similarly, several commands take time parameters specified in
clock ticks. One can specify a value for these parameters in seconds
using the "TICKS()" macro - for example "cycle_ticks=TICKS(0.001)"
would result in "cycle_ticks=16000" on a micro-controller with a 16Mhz
clock.
