arm64: sysreg: Correct sign definitions for EIESB and DoubleLock

[ Upstream commit f4d4ebc84995178273740f3e601e97fdefc561d2 ]

The `ID_AA64MMFR4_EL1.EIESB` field, is an unsigned enumeration, but was
incorrectly defined as a `SignedEnum` when introduced in commit
cfc680bb04c5 ("arm64: sysreg: Add layout for ID_AA64MMFR4_EL1"). This is
corrected to `UnsignedEnum`.

Conversely, the `ID_AA64DFR0_EL1.DoubleLock` field, is a signed
enumeration, but was incorrectly defined as an `UnsignedEnum`. This is
corrected to `SignedEnum`, which wasn't correctly set when annotated as
such in commit ad16d4cf0b4f ("arm64/sysreg: Initial unsigned annotations
for ID registers").
