[PATCH] docs: staging: fix various typos and grammar issues

[Zhang Xiaolei]

Fix a few typographical and grammatical issues across several
staging documentation files to improve readability:
- crc32.rst: replace "decide in" with "decide on"
- lzo.rst: replace "independent on" with "independent of"
- remoteproc.rst: fix word order in dependent clause
- static-keys.rst: add hyphen to "low-level"

 This produces a 40-bit (rather than a 33-bit) intermediate remainder,
 and the correct multiple of the polynomial to subtract is found using
 a 256-entry lookup table indexed by the high 8 bits.
