arm64: esr: Define ESR_ELx_EC_* constants as UL
Add explicit casting to prevent expantion of 32th bit of u32 into highest half of u64 in several places. For example, in inject_abt64: ESR_ELx_EC_DABT_LOW << ESR_ELx_EC_SHIFT = 0x24 << 26. This operation's result is int with 1 in 32th bit. While casting this value into u64 (esr is u64) 1 fills 32 highest bits. Found by Linux Verification Center (linuxtesting.org) with SVACE.
