[RFC] [WIP] ft2232_spi: reintroduce generic GPIOL control

This reintroduces a reworked version of the GPIOL pin control first
introduced in commit 3207844 (CB:49637), which was reverted in commit
6518cf3 (CB:55692).

Original commit message (will be reworked/corrected later):

Adds a new arg "gpiol" to allow the four FT2232 GPIOL pins to be set to
any combination of high, low or high-impedance.

The existing arg "csgpiol", is intended to function as an additional
"cs" signal, allowing pins to be set high but not low. This patch
preserves the csgpiol arg for backward compatibility. In the event that
both arguments are specified, gpiol is used.

TODOs:
 - discuss merging `csgpiol` into `gpiol` as 'C' (see RFC comment)
 - reword commit message
 - man page for both `csgpiol`, `gpiol`
