[U-Boot] [PATCH 1/2] net: zynq_gem: Use wait_for_bit with non breakable

From: Siva Durga Prasad Paladugu siva.durga.paladugu@xilinx.com

Use wait_for_bit to be non breakable as using it with breakable causes issue of un interruptible auto negotiation. This is due to the ctrlc pressed will taken for wait_for_bit() abort during phy_read() and hence not coming out of auto negotiation.
