mule-attiny.sh: support Tiger v1.1
Tiger v1.1 has the UPDI lanes cut by default unless
ATtiny_GATE_CONTROL_d (GPIO0_C4) is pulled high.
Let's toggle that GPIO before flashing so that the UPDI can go through
to the ATtiny.
Since that GPIO was used for UART0 in Tiger v1.0, it is not supported
anymore (but those were engineering samples anyway).
Relates-to: TIGR-192
