Fix following DTC warnings for all x86 boards.

There was a warning like:
Warning (unit_address_vs_reg): Node /microcode/update@0 has a unit name, but no 
reg property
Warning (unit_address_vs_reg): Node /microcode/update@1 has a unit name, but no 
reg property

I replaced "udpate@" with "update_". Please test
this patch

This warnings pop up with the DTC compiler:
$ /tmp/dtc/dtc -v
Version: DTC 1.4.1-gbeef80b8

This fixes the compile warnings for:
https://travis-ci.org/u-boot/u-boot/jobs/122880432

see:
https://travis-ci.org/hsdenx/u-boot/jobs/123281030

Tested with sandbox, following steps work as before:

make sandbox_defconfig
make
./u-boot -d u-boot.dtb

but "ut all" drops warnings ... but this patch introduced
no new warnings ...
