Andy Yan 8e5c859386 scripts: add mkmultidtb.py to package multiple dtbs to resource.img 
People sometimes want to package multiple dtbs to resource.img for
a baseboard which may has several hardware variants. And on the
hardware design side, may use adc value or gpio level to indicate
the hardware id, so we encode the hardware id information at the
suffix of the dtb file name.

For example:

DTBS['PX30-EVB'] = OrderedDict([('px30-evb-ddr3-v10', '#_saradc_ch0=1024'),
                                ('px30-evb-ddr3-lvds-v10', '#_saradc_ch0=512')])

DTBS['RK3308-EVB'] = OrderedDict([('rk3308-evb-dmic-i2s-v10', '#_saradc_ch3=288'),
                                  ('rk3308-evb-dmic-pdm-v10', '#_saradc_ch3=1024'),
                                  ('rk3308-evb-amic-v10', '#_saradc_ch3=407')])

DTBS['RK3308-SWEEPER'] = OrderedDict([('rk3308-sweeper-v10', '#gpio0a2=0'),
				      ('rk3308-sweeper-v11', '#gpio0a2=1')])

When you run the script like:
$ scripts/mkmultidtb.py RK3308-EVB

The script will package all the dtbs you list in DTBS['PX30-EVB']
to resource.img with a new name that suffix with hardware id
information:

rk3308-evb-dmic-pdm-v10#_saradc_ch3=1024.dtb
rk3308-evb-dmic-i2s-v10#_saradc_ch3=288.dtb
rk3308-evb-amic-v10#_saradc_ch3=407.dtb

And the script will also make another copy of the fist dtb
file which you list in the OrderedDict named as rk-kernel.dtb

Check the content of resource.img by command: hd resource.img | less
