Subject: [RFC PATCH 2/2] ARM: OMAP4: setup CPU model name during ID initialisation

Set up the CPU model name during OMAP ID initialisation
so it will be displayed in /proc/cpuinfo:

/ # cat proc/cpuinfo
processor       : 0
model name      : ARMv7 Processor rev 10 (v7l)
BogoMIPS        : 1590.23
Features        : swp half thumb fastmult vfp edsp thumbee neon vfpv3 tls
CPU implementer : 0x41
CPU name        : OMAP4470 ES1.0 HS
CPU architecture: 7
CPU variant     : 0x2
CPU part        : 0xc09
CPU revision    : 10
[...]
