imx8m: lock id_swap_bypass bit in tzc380 enable
According to TRM for i.MX8M Nano and Plus, GPR10 register contains lock
bit for TZASC_ID_SWAP_BYPASS bit. This bit is required to be set in
order to avoid AXI bus errors when GPU is enabled on the platform.
TZASC_ID_SWAP_BYPASS bit is alread set for all imx8m applicable
derivatives, but is missing a lock settings to be applied.
Set the TZASC_ID_SWAP_BYPASS_LOCK bit for those derivatives which have
it implemented.
Since we're here, provide also names to bits from TRM instead of using
BIT() macro in the code.
