commit 7c8f821e5dde ("i2c: rcar_i2c: Set the slave address from
rcar_i2c_xfer") blindly called rcar_i2c_set_addr() with read argument
always set to 1 during xfer which introduced read/write errors, whereas
earlier rcar_i2c_read_common() called rcar_i2c_set_addr() with read set to
1 and rcar_i2c_write_common() called rcar_i2c_set_addr() with read set 0.

Fix for the case of a U-Boot configuration with CONFIG_SPL,
CONFIG_I2C_MUX, CONFIG_I2C_MUX_PCA954x, no CONFIG_SPL_DM and no
CONFIG_SPL_I2C_MUX. Without this fix linking of pca954x fails because
dm_write_i2c does not exist because CONFIG_SPL_DM is not defined.

This patch fixes a few issues noticed, when testing this new driver on
ARM Octeon TX2 again. Here the details:

- Remove "common.h" header inclusion
- Use correct THP define on Octeon TX2
- Octeon TX2 uses the same compatible as Octeon TX. We can't distinguish
  both platforms this way. Remove the unused "cavium,thunder2-99xx-twsi"
  compatible and add a check to the Octeon TX2 specific
  "cavium,thunderx-i2c" so that the correct driver data is selected.
- Removed "struct pci_device_id" definition and U_BOOT_PCI_DEVICE()
  as its not needed for the PCI based probing on Octeon TX2

When you enable CONFIG_OF_LIVE, you will end up with a lot of
conversions.

To help this tedious work, this commit converts devfdt_get_addr_ptr()
to dev_read_addr_ptr() by coccinelle. I also removed redundant casts
because dev_read_addr_ptr() returns an opaque pointer.

To generate this commit, I ran the following semantic patch
excluding include/dm/.

  type T;
  expression dev;

According to the description of devfdt_get_addr_ptr, this function should
return NULL on failure, but currently it returns (void *)FDT_ADDR_T_NONE.

Fix this by making devfdt_get_addr_ptr return NULL on failure, as
described in the function comments. Also, update the drivers currently
checking (void *)FDT_ADDR_T_NONE to check for NULL.

Zynq/ZynqMP/Versal IPs should be possible to called also from Microblaze in
PL and vice versa. That's why change dependencies and do not limit enabling

Changes in relation to FriendlyARM's U-Boot nanopi2-v2016.01:
- i2c/nx_i2c.c: Some adaptions mainly because of changes in
  "struct udevice".
- several Bugfixes in nx_i2c.c.
- the driver has been for s5p6818 only. Code extended appropriately
  in order s5p4418 is also working.
- "probe_chip" added.
- pinctrl-driver/dt is used instead of configuring the i2c I/O-pins
  in the i2c-driver.
- '#ifdef CONFIG...' changed to 'if (IS_ENABLED(CONFIG...))' where
  possible (and similar).
- livetree API (dev_read_...) is used instead of fdt one (fdt...).
