build: disable suffix rules globally

This change centralises the logic that disables the default suffix rules
that Make provides. These rules are a hold-over from legacy standards of
Make, and occasionally conflict with our rules.

Use TOOL_ADD_IMG_PAYLOAD instead of TOOL_ADD_IMG to generate the BL31

binaries and FIP in a single command. Else, as TOOL_ADD_IMG evaluate
the existence of the file before building it, we have a build error.

fix(stm32mp2): enable timer earlier in BL31

The timer is required when setting console. In BL2 the timer init is
done in clock driver init. This is not the case in BL31. So initialize
the generic_delay_timer_init() just after stm32mp2_clk_init() call.
This is required after the recent changes in timer framework [1].
