[media] drx-j: add a driver for Trident drx-j frontend

Add support for the Trident DRX-J driver, including a card profile for the
PCTV 80e which uses the chip.

Thanks to Trident for allowing the release of this code under a BSD license,
and of course Hauppauge/PCTV for pushing for its release to the community.

[pdickeybeta@gmail.com: modified to fix compilation errors and also to move
 the driver files from the drx39xy subdirectory to the frontends directory]

[m.chehab@samsung.com: fix merge conflicts, commented drx-j compilation and
 added EM28XX_R06_I2C_CLK setup also to the board setup]

+/*
+* Comments about DRXDAP_MAX_WCHUNKSIZE in single or multi master mode and
+* in combination with short and long addressing format. All text below
+* assumes long addressing format. The table also includes information
+* for short ADDRessing format.
+*
+* In single master mode, data can be written by sending the register address
+* first, then two or four bytes of data in the next packet.
+* Because the device address plus a register address equals five bytes,
+* the mimimum chunk size must be five.
+* If ten-bit I2C device addresses are used, the minimum chunk size must be six,
+* because the I2C device address will then occupy two bytes when writing.
+*
+* Data in single master mode is transferred as follows:
+* <S> <devW>  a0  a1  a2  a3  <P>
+* <S> <devW>  d0  d1 [d2  d3] <P>
+* ..
+* or
+* ..
+* <S> <devW>  a0  a1  a2  a3  <P>
+* <S> <devR> --- <P>
+*
+* In multi-master mode, the data must immediately follow the address (an I2C
+* stop resets the internal address), and hence the minimum chunk size is
+* 1 <I2C address> + 4 (register address) + 2 (data to send) = 7 bytes (8 if
+* 10-bit I2C device addresses are used).
+*
+* The 7-bit or 10-bit i2c address parameters is a runtime parameter.
+* The other parameters can be limited via compile time switches.
