ARM: dt: tegra: cardhu: split dts file for support multiple board versions

There is multiple version of cardhu starting from A01 to A07.
Cardhu A01 and A03 are not supported. Cardhu A02 will have
different sets of GPIOs for fixed regulator compare to
cardhu A04. The Cardhu A05, A06, A07 are compatibe with A04.
Based on cardhu version, the related dts file need to be chosen
like for cardhu A02, use tegra30-cardhu-a02.dts, cardhu A04 and
more, use tegra30-cardhu-a04.dts.
This patch create the DTS file A02 and A04 and convert tegra30-cardhu.dts
as dts include file.

+/**
+ * This file contains common DT entry for all fab version of Cardhu.
+ * There is multiple fab version of Cardhu starting from A01 to A07.
+ * Cardhu fab version A01 and A03 are not supported. Cardhu fab version
+ * A02 will have different sets of GPIOs for fixed regulator compare to
+ * Cardhu fab version A04. The Cardhu fab version A05, A06, A07 are
+ * compatible with fab version A04. Based on Cardhu fab version, the
+ * related dts file need to be chosen like for Cardhu fab version A02,
+ * use tegra30-cardhu-a02.dts, Cardhu fab version A04 and later, use
+ * tegra30-cardhu-a04.dts.
+ * The identification of board is done in two ways, by looking the sticker
+ * on PCB and by reading board id eeprom.
+ * The stciker will have number like 600-81291-1000-002 C.3. In this 4th
+ * number is the fab version like here it is 002 and hence fab version A02.
+ * The (downstream internal) U-Boot of Cardhu display the board-id as
+ * follows:
+ * BoardID: 0C5B, SKU: 0A01, Fab: 02, Rev: 45.00
+ * In this Fab version is 02 i.e. A02.
+ * The BoardID I2C eeprom is interfaced through i2c5 (pwr_i2c address 0x56).
+ * The location 0x8 of this eeprom contains the Fab version. It is 1 byte
+ * wide.
