dt-bindings: mtd: amlogic,meson-nand: support fields for boot ROM code
Boot ROM code on Meson requires that some pages on NAND must be written
in special mode: "short" ECC mode where each block is 384 bytes and
scrambling mode is on. Such pages are located on the chip in the
following way (for example):
[ p0 ][ p1 ][ p2 ][ p3 ][ p4 ][ p5 ][ p6 ][ p7 ] ... [ pN ]
^ ^ ^ ^
pX is page number "X". "^" means "special" page used by boot ROM - e.g.
every 2nd page in the range of [0, 7]. Step (2 in example is set by
'amlogic,boot-page-step' field. Last page in range (7 in example) is
set by 'amlogic,boot-pages' field.
