Ayke van Laethem 6389e45d99 all: replace ReadRegister with AsmFull inline assembly
This makes AsmFull more powerful (by supporting return values) and
avoids a compiler builtin.

Go

package avr
// Run the given assembly code. The code will be marked as having side effects,
// as it doesn't produce output and thus would normally be eliminated by the
// optimizer.
func Asm(asm string)
// Run the given inline assembly. The code will be marked as having side
// effects, as it would otherwise be optimized away. The inline assembly string
// recognizes template values in the form {name}, like so:
//
// avr.AsmFull(
// "str {value}, {result}",
// map[string]interface{}{
// "value": 1
// "result": &dest,
// })
//
// You can use {} in the asm string (which expands to a register) to set the
// return value.
