Subject: [PATCH] ARM: Fix __show_regs output timestamps

Multiple line formats are not preferred as the second and
subsequent lines may not have timestamps.

Lacking timestamps makes reading the output a bit difficult.
This also makes arm/arm64 output more similar.

Previous:

[ 1514.093231] pc : [<bf79c304>]    lr : [<bf79ced8>]    psr: a00f0013
sp : ecdd7e20  ip : 00000000  fp : ffffffff

New:

[ 1514.093231] pc : [<bf79c304>]    lr : [<bf79ced8>]    psr: a00f0013
[ 1514.105316] sp : ecdd7e20  ip : 00000000  fp : ffffffff
