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) due to breakage.

This change introduces a new argument `gpiolX` to allow use of the four
GPIOL pins either as generic gpios or as additional CS# signal(s). `X`
specifies the GPIOL pin (0-3) to be set to one of [HLC] with the
following meaning:

* H - set the pin as output high
* L - set the pin as output low
* C - use the pin as additional CS# signal

The third value, `C`, aims to replace the parameter `csgpiol`, that is
now marked as deprecated and can be removed at some point in the future.
`gpiol` and `csgpiol` are mutually exclusive and use of both results in
an error.

Multiple pins may be set by specifying the parameter multiple times.

Documentation was updated/added accordingly.
