[media] dib0700: add initial code for PCTV 340e by Davide Ferri
This is initial code written by Davide Ferri for the PCTV 340e, including a new xc4000 driver. I am checking in all the code unmodified, and making no assertions about its quality (other than confirming it compiles).

114 Basic firmware description. This will remain with
115 the driver for documentation purposes.
116
117 This represents an I2C firmware file encoded as a
118 string of unsigned char. Format is as follows:
119
120 char[0 ]=len0_MSB -> len = len_MSB * 256 + len_LSB
121 char[1 ]=len0_LSB -> length of first write transaction
122 char[2 ]=data0 -> first byte to be sent
123 char[3 ]=data1
124 char[4 ]=data2
125 char[ ]=...
126 char[M ]=dataN -> last byte to be sent
127 char[M+1]=len1_MSB -> len = len_MSB * 256 + len_LSB
128 char[M+2]=len1_LSB -> length of second write transaction
129 char[M+3]=data0
130 char[M+4]=data1
131 ...
132 etc.
133
134 The [len] value should be interpreted as follows:
135
136 len= len_MSB _ len_LSB
137 len=1111_1111_1111_1111 : End of I2C_SEQUENCE
138 len=0000_0000_0000_0000 : Reset command: Do hardware reset
139 len=0NNN_NNNN_NNNN_NNNN : Normal transaction: number of bytes = {1:32767)
140 len=1WWW_WWWW_WWWW_WWWW : Wait command: wait for {1:32767} ms
141
142 For the RESET and WAIT commands, the two following bytes will contain
143 immediately the length of the following transaction.
