mtd: tests: introduce helper functions This introduces the helper functions which can be used by several mtd/tests modules. The following three functions are used all over the test modules. - mtdtest_erase_eraseblock() - mtdtest_scan_for_bad_eraseblocks() - mtdtest_erase_good_eraseblocks() The following are wrapper functions for mtd_read() and mtd_write() which can simplify the return value check. - mtdtest_read() - mtdtest_write() All helpers are put into a single .c file and it will be linked to every test module later. The code will actually be copied to every test module, but it is fine for our small test infrastructure.
