[U-Boot] [PATCH 27/28] SPEAr : Ethernet issue workaround is not needed when uboot is acting as flashing

[Vipin KUMAR]

From: Vipin KUMAR <vipin.kumar at st.com>

Ethernet/UHC issue workaround which resets the SoC has an unexpected effect
while using uboot as flashing utils firmware. So, excluding the changes for
uboot built as usbtty firmware

Enable overwriting of env variables. The env variables ethaddr, serial# etc
support a feture of being written only once. Though this feature is bypassed
using this patch
