ata: use COMMAND_LINE_SIZE for ata_force_param_buf[] size
Use COMMAND_LINE_SIZE instead PAGE_SIZE for ata_force_param_buf[]
size as libata parameters buffer doesn't need to be bigger than
the command line buffer.
For many architectures this results in decreased libata-core.o
size (COMMAND_LINE_SIZE varies from 256 to 4096 while the minimum
PAGE_SIZE is 4096).
Code size savings on m68k arch using (modified) atari_defconfig:
text data bss dec hex filename
