Subject: [PATCH] sh_eth: add/use RMCR.RNC bit

Declare 'enum EMCR_BIT' containing the single member for the RMCR.RNC bit and
replace bare numbers in the driver by  this mnemonic.

Suggested-by: David Miller <davem@...emloft.net>
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>

This patch is against DaveM's 'net.git' repo but it intended for 'net-next.git'
repo -- it's  because 'net-next.git' doesn't contain the required Simon Horman's
patch yet.
