nand: omap2: Remove horrible ifdefs to fix module probe
The current code abuses ifdefs to determine if the selected ECC scheme
is supported by the running kernel. As a result the code is hard to read,
and it also fails to load as a module.
This commit removes all the ifdefs and instead introduces a function
omap2_nand_ecc_check() to check if the ECC is supported by using
IS_ENABLED(CONFIG_xxx).
Since IS_ENABLED() is true when a config is =y or =m, this change fixes the
module so it can be loaded with no issues.
