net: fec: Ensure that initialization is done prior to request_irq()
Currently request_irq() is called prior to fec_enet_init() and fec_ptp_init(),
which causes the following crash on a mx53qsb:
Unable to handle kernel NULL pointer dereference at virtual address

Ensure that such initialization functions are called prior to requesting the
interrupts, so that all necessary the data structures are in place when the
irqs occur.
