core/linux-am33x to 4.14.3-2 (#1546)

Browse source 
Add mcp23s08 and tps65217 backlight drivers, which are required to get
use of chiliboard LCD shield. mcp23s08 is a I2C GPIO expander needed
to enable LCD.

Add I2C GPIO expander needed to put LCD_EN pin high. Note, than
previously that was not needed, because initial batch of LCD shields
had pull-up resistors instead of pull-down.

Update checksums and bump up pkgrel.
