[PATCH] TI DaVinci EMAC: delay DaVinci EMAC initialization

[PATCH] TI DaVinci EMAC: delay DaVinci EMAC initialization

[Sudhakar Rajashekhara]

On TI's DA850/OMAP-L138 EVM, MAC address is stored in SPI
flash which is accessed using MTD interface.

This patch delays the initialization of DaVinci EMAC driver
by changing module_init to late_initcall. This helps SPI and
MTD drivers to get initialized before EMAC thereby enabling
EMAC driver to read the MAC address while booting and use it.

Tested with NFS on DM644x, DM6467, DA830/OMAP-L137 and
DA850/OMAP-L138 EVMs.
