target/arm: Allow use of upper 32 bits of TBFLAG_A64
The TBFLAG_A64 TB flag bits go in flags2, which for AArch64 guests we know is 64 bits. However at the moment we use FIELD_EX32() and FIELD_DP32() to read and write these bits, which only works for bits 0 to 31. Since we're about to add a flag that uses bit 32, switch to FIELD_EX64() and FIELD_DP64() so that this will work.
