nvmem: layouts: Switch from crc32() to crc32_le()

u_boot_env_parse() calls crc32() from within a scope that has a uint32_t
variable named crc32.  This works only because crc32() is actually a
macro that expands to crc32_le().  I'm planning to make it an inline
function instead, which will make the usual C scoping rules apply to it.
Therefore, update u_boot_env_parse() to be compatible with that.  To do
so, just call crc32_le() directly instead of using the crc32() alias.
(An alternative would be to rename the local variable.)
