spi: aspeed: Replace VLA parameter with flat pointer in calibration helper

Browse source

aspeed_spi_ast2600_optimized_timing() declared its buffer argument as a
variable-length array parameter (u8 buf[rows][cols]), which causes a
sparse warning. Replace the VLA parameter with a plain u8 * and compute
the 2-D index manually. The corresponding call site is also updated.
