Suppress spurious deprecated declaration warnings
Some generic compatibility functions emit deprecated declaration warnings even when platforms do not use the deprecated functions directly. This can be confusing. Suppress these warnings by using: `#pragma GCC diagnostic ignored "-Wdeprecated-declarations"` Also emit a runtime warning if the weak plat/common implemntation of plat_get_syscnt_freq2() is used, as this implies the platform has not migrated from plat_get_syscnt_freq(). The deprecated declaration warnings only help detect when platforms are calling deprecated functions, not when they are defining deprecated functions. Fixes ARM-software/tf-issues#550 Change-Id: Id14a92279c2634c1e76db8ef210da8affdbb2a5d Signed-off-by: Dan Handley <dan.handley@arm.com>
