Only the call in `spi_flash_cmd_write_page_program` uses non-constant
values for the array length. However, the value for `data_len` has an
upper bound: `flash->page_size` is set to `1U << vi->page_size_shift`
which depends on the flash chip vendor info, and the largest value it
can currently have is 8. Thus, the maximum page size is currently 256.
Define the `MAX_FLASH_CMD_DATA_SIZE` macro to place an upper bound on
the amount of data that can be written in one command. Then, use this
value to allocate a fixed-size buffer in `spi_flash_cmd_write`. Also,
add a check to prevent buffer overflow problems. Finally, ensure that
the `spi_flash_cmd_write_page_program` function always writes no more
than 256 bytes of data when using the `spi_flash_cmd_write` function.
Tested on Asrock B85M Pro4 (Winbond W25Q64FV), MRC cache still works.
