staging: sm750fb: remove unnecessary volatile qualifiers

The use of 'volatile' for memory-mapped I/O pointers is discouraged
in the Linux kernel as per
Documentation/process/volatile-considered-harmful.rst.

This patch removes the unnecessary 'volatile' qualifiers from the
lynx_accel struct members, improving code quality and maintainability.
