Generally at most 1 blank line is the standard style for DT schema files. Remove the few cases with more than 1 so that the yamllint check for this can be enabled.

|
Number of pages starting from offset 0, where a special ECC
|
|
configuration must be used because it is accessed by the ROM
|
|
code. This ECC configuration uses 384 bytes data blocks.
|
|
Also scrambling mode is enabled for such pages.

description:
|
|
Interval between pages, accessed by the ROM code. For example
|
|
we have 8 pages [0, 7]. Pages 0,2,4,6 are accessed by the
|
|
ROM code, so this field will be 2 (e.g. every 2nd page). Rest
|
|
of pages - 1,3,5,7 are read/written without this mode.
