The setup_max_cpus variable is only defined if CONFIG_SMP is set. Add
a preprocessor condition to avoid the following compilation error if
CONFIG_SMP is not set:
arch/arm/include/asm/trusted_foundations.h: In function
'register_trusted_foundations':
arch/arm/include/asm/trusted_foundations.h:57:2: error: 'setup_max_cpus'
undeclared (first use in this function)

Hi Stephen,
This patch has been originally submitted through Russell's patch tracker,
where it has stayed untouched for ~3 weeks now. Considering that this
fixes a compilation error and should thus be made available quickly, and
that Tegra is the only user of Trusted Foundations, would you agree to take
it into your tree?
