ARM: dts: at91: sam9x60: Fix the label numbering for the flexcom functions

Fixed the label numbering of the flexcom functions so that all
13 flexcom functions of sam9x60 are in the following order when the missing
flexcom functions are added:

flx0: uart0, spi0, i2c0
flx1: uart1, spi1, i2c1
flx2: uart2, spi2, i2c2
flx3: uart3, spi3, i2c3
flx4: uart4, spi4, i2c4
flx5: uart5, spi5, i2c5
flx6: uart6, i2c6
flx7: uart7, i2c7
flx8: uart8, i2c8
flx9: uart9, i2c9
flx10: uart10, i2c10
flx11: uart11, i2c11
flx12: uart12, i2c12
