Subject: [PATCH v3 06/17] mtd: spinand: Define default ctrl_ops in the core

Add default ctrl_ops in the core, which can be used when the op
templates are commonly used ones. Till now, the core had used only
fixed ctrl operations, so the default 'ctrl_ops' is just these ops
macros initialized with default arguments. The default protocol is
1S_1S_1S.
