mmc: cast u8 to unsigned long long to avoid unexpected error
card->ext_csd.enhanced_area_offset is defined as "unsigned long long",
and, ext_csd[] is defined as u8.
unsigned long long data might have strange data if first bit of ext_csd[]
was 1. this patch cast it to (unsigned long long)
Special thanks to coverity <http://www.coverity.com>
ex)
u8 data8;
u64 data64;
data8 = 0x80;
data64 = (data8 << 24); // 0xffffffff80000000
data64 = (((unsigned long long)data8) << 24); // 0x80000000;
