[PATCH] ARM: dts: vexpress: Replace '_' with '-' in node names

[Sudeep Holla]

The latest DTC throws warnings for character '_' in the node names.

Warning (node_name_chars_strict): /sysreg at 10000/sys_led: Character '_' not recommended in node name
Warning (node_name_chars_strict): /sysreg at 10000/sys_mci: Character '_' not recommended in node name
Warning (node_name_chars_strict): /sysreg at 10000/sys_flash: Character '_' not recommended in node name

The general recommendation is to use character '-' for all the node names.
This patch fixes the warnings following the recommendation.
