ArmPlatformPkg: fix undefined reference to memcpy

When building ArmJuno, (-flto -Os build only) fails with:
ArmPlatformPkg\Library\PL031RealTimeClockLib/PL031RealTimeClockLib.c:224:
undefined reference to `memcpy'
Clearly STATIC was intended for the day of month lookup table so
that the compiler doesn't have to generate code to create the table
at runtime each time the function is entered. Apparently -flto
triggers use of memcpy for creating the table. making the table
static removes the need for the compiler to create it at runtime.
Thanks,
Scott
