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.

dt-bindings: nand: meson: make ECC properties dependent
...
ECC properties 'nand-ecc-strength' and 'nand-ecc-step-size' depends on
each other, so they must be both either set or not set. In first case
ECC core will try to use these values if possible (by checking ECC caps
provided by driver), in second case ECC core will select most optimal
values for both properties.

...
Meson NAND supports both 512B and 1024B ECC step size, so replace
'const' for only 1024B step size with enum for both sizes.

...
Ensure all raw NAND chip properties are valid by referencing the
relevant schema and set unevaluatedProperties to false in the NAND chip
section to avoid spurious additions of random properties.
