Eugen Hristev dbf500b557 configs: at91: sama7g5ek: enable CONFIG_PHANDLE_CHECK_SEQ
CONFIG_PHANDLE_CHECK_SEQ will allow different sequence number for nodes
that have the same name, but they are different.
In sama7g5ek case, there are multiple 'i2c@600' nodes which are child
nodes of different parent 'flexcom' nodes.
These are different i2c busses even if the node is the same, and have to be
differentiated.
Without this config, the sequence number 0 is reused for two i2c busses, and
this is something that we have to avoid:

Looking for 'i2c' at 4704, name i2c@600
   - serial0, /ahb/apb/serial@e1824200
   - i2c0, /ahb/apb/flexcom@e181c000/i2c@600

i2c_post_bind: i2c@600, seq=0
