In the "ast2700_a0_resets" function, the hardcoded value "0x00000800" is set in SCU hw-strap1 (CPU DIE), and in "ast2700_a0_resets_io" the hardcoded value "0x00000504" is set in SCUIO hw-strap1 (IO DIE). Both values cannot be set via the SOC layer. The value of "s->hw_strap1" is set by the SOC layer via the "hw-strap1" property. Update the "aspeed_ast2700_scu_reset" function to set the value of "s->hw_strap1" in both the SCU and SCUIO hw-strap1 registers.
