Earlier I had pin 20 as the default SCK1, but card shows that pin 32 is
the default pin

Added in the additional SPI pins
MISO 39
MOSI 28
SCK 27

Tested with my ILI9341_t3n (SPIN) version.  Will also
Add to ILI9341_t3.

With the new beta boards, for those users who don't need an SDCard for
their project, it would be great to allow them to use the 6 IO pins
associated with the SDCARD for other purposes.  This would probably
require a cheap adapter, but these are nice signals to be able to be
used.  They include:

SPI1: SCK, MISO, MOSI, CS0-2
Serail2: TX/RX
Serial4: TX/RX
I2C1: SCL/SDA

This change adds support for GPIO, SPI, Serial2 and Serial4
