lsi53c895a: fix endianness issues

lsi_ram_read*() and lsi_ram_write*() are not consistent, one uses
leXX_to_cpu() the other uses nothing. As the comment above the RAM
declaration says: "Script ram is stored as 32-bit words in host
byteorder.", remove the leXX_to_cpu() calls.

This fixes the boot of an ARM versatile machine on MIPS and PowerPC
hosts.
