[U-Boot] [PATCH 16/17] Move low level eNET board init into dedicated sections

[Graeme Russ]

This patch is in readiness for moving all u-boot code + data from Flash to
RAM. Low level init code is not needed after bootstrap and therefore does
not need to be copied. Moving this code into dedicated sections makes it
easier
