[U-Boot] [PATCH] nios2: change size_t to fix format warning for gcc 4.7.3

[Thomas Chou]

The gcc-4.7.3 in lastest nios2 toolchain generated lots of warning on
type mismatch. So change typedef of size_t to unsigned int, followed
those of arm and mips arch.

spi_flash.c: In function 'spi_flash_read_write':
spi_flash.c:42:3: warning: format '%zu' expects argument of type
  'size_t', but argument 2 has type 'long unsigned int' [-Wformat]
