From: Hongbo Zhang <hongbo.zhang@linaro.org>

The arch/arm/odp_sysinfo_parse.c is currently a symlink to
arch/linux/odp_sysinfo_parse.c, but in fact there should be defferences
between them.

A separated real arch/arm/odp_sysinfo_parse.c is created for ARM, and
the model_str is set to a general "ARM", which is much better then the
general defaul "UNKNOWN" although not so accurate in detailed ARM CPU
model string.

ODP_DBG("TODO: true values should be implemented when possible\n") is
added for ARM too, this means when possible true values can be implemented
for ARM, and only ARM odp_cpuinfo_parser() is updated, while the general
defaul odp_cpuinfo_parser() should be leave there unchanged. In other
words the current implementation for ARM is a temporary work around, but
for the generic default dummy data has to be accepted.

ODP_DBG("Refer to https://bugs.linaro.org/show_bug.cgi?id=1870\n") is
deleted, because this bug describes another thing, eg in previous code,
only cpu_hz_max[0] and model_str[0] were set, the others such as
cpu_hz_max[1...n-1] and model_str[1...n-1] were missing, it isn't related
with the value itself is dummy or not, and this bug was already fixed.
