Miquel Raynal f7190b6101 mtd: rawnand: Clarify conditions to enable continuous reads
commit 828f6df1bc upstream.

The current logic is probably fine but is a bit convoluted. Plus, we
don't want partial pages to be part of the sequential operation just in
case the core would optimize the page read with a subpage read (which
would break the sequence). This may happen on the first and last page
only, so if the start offset or the end offset is not aligned with a
page boundary, better avoid them to prevent any risk.
