09da8fb651 armv7/8 cache:CSSELR should be set before getting cache info
According to the ARMv7a/r/m and ARMv8m architecture manuals
The allowed values are

1 Instruction cache.

"One CCSIDR is implemented for each cache that can be accessed by the processor. CSSELR selects which Cache Size ID Register is accessible, see c0, Cache Size Selection Register (CSSELR)."
