Both TT-connect S2-3600 and Pinnacle PCTV Sat HDTV are using
Intersil ISL6423 as LNB voltage regulator. This makes
TT-connect S2-3650 CI the only device which uses STM LNBP22 regulator
which is currently used for all devices driven by pctv452e driver.
This patch fixes this by creating an exception for TT-connect S2-3650 CI
to continue to use STM LNBP22 while all others now using correct ISL6423
driver which makes DiSEqC/EN50494 comands which involve voltage changes
now working on the other devices (which didn't work before).

This driver still uses the USB stack for DMA transfers,
which is broken for a long time. I almost dropped this driver,
as there's a high chance that nobody is using it with upstream
Kernels, as we didn't receive any bug reports.
As fixing this won't be hard, I ended opting to fix.
While here, I dropped an ugly hack that implemented read via
a separate function that was just doing a memcpy().
It should be noticed that, during the init phase, there's
a "b4" register that were never initialized, as its buffer
were used just to store the results of "b3" initialization.

In `gmin_v2p8_ctrl()` there's a call to this function but the
possibility of a NULL was not checked before its being dereferenced,

struct gmin_subdev *gs = find_gmin_subdev(subdev);
/* v------Dereferenced here */
if (gs->v2p8_gpio >= 0) {
