ast27x0: Fix missing SCU module reset for SSP and TSP initialization

Fix SSP and TSP boot failure caused by missing SCU reset control. This commit adds
SCU modrst1/modrst2 reset logic to ssp_init() and tsp_init(). Without proper reset
release, SSP and TSP CPUs stay in reset and cannot start. Also adds missing SCU
register fields and reset bit definitions for SSP (BIT(30)) and TSP (BIT(9)).

Fixes: 80768e4 ("ast27x0: Initialize and enable SSP/TSP using SCU with reserved-
memory from DTB")
