bbremote: implement i2c read/write support
Extend the bbremote script with operations to perform binary i2c
read/write operations.
E.g.:
barebox:/ i2c_read -b 0 -a 0x68 -r 0x06A0 -c 4 -w
0x8f 0x30 0x00 0x00
barebox:/ i2c_write -b 0 -a 0x68 -r 0x06A0 -w 0x87 0x30 0x00 0x00
barebox:/ i2c_read -b 0 -a 0x68 -r 0x06A0 -c 4 -w
0x87 0x30 0x00 0x00
barebox:/ i2c_write -b 0 -a 0x68 -r 0x06A0 -w 0x8f 0x30 0x00 0x00
barebox:/ i2c_read -b 0 -a 0x68 -r 0x06A0 -c 4 -w
0x8f 0x30 0x00 0x00
