module/icp/asm-arm/sha2: enable non-SIMD asm kernels on armv5/6

Browse Source 
My merged pull request #15557 fixes compilation of sha2 kernels on arm
v5/6. However, the compiler guards only allows sha256/512_armv7_impl to
be used when __ARM_ARCH > 6. This patch enables these ASM kernels on all
arm architectures. Some compiler guards are adjusted accordingly to
avoid the unnecessary compilation of SIMD (e.g., neon, armv8ce) kernels
on old architectures.
