ata: libata-scsi: fix ata_dsm_trim_pages() kernel-docgrafted

make htmldocs fails with:

  Documentation/driver-api/libata:604: ./drivers/ata/libata-scsi.c:2301:
  ERROR: Unexpected indentation. [docutils]

The Return: section of ata_dsm_trim_pages() ends its first sentence with
a colon and continues with an indented bullet list. reStructuredText
requires a blank line before an indented block, so docutils chokes on
the list.

Simply adding the missing blank line does not work either: Return: is a
kernel-doc "special section", which is terminated by the first blank
line, so the bullet list would end up in the Description section,
detached from the sentence introducing it.

Spell the two bounds out as prose instead, so that the Return: section
stays self-contained. Documentation-only change.

Fixes: e64e6b5dc867 ("ata: libata-scsi: scale DSM TRIM payload by MAX PAGES PER DSM COMMAND")

+ * Reset driver for the Mobileye EyeQ5, EyeQ6L, EyeQ6H and EyeQ7H platforms.
+ *
+ * Controllers live in a shared register region called OLB. EyeQ5 and EyeQ6L
+ * have a single OLB instance for a single reset controller. EyeQ6H has seven
+ * OLB instances; three host reset controllers. EyeQ7H has fourteen OLB instances;
+ * eleven host reset controllers.
+ *
+ * Each reset controller has one or more domain. Domains are of a given type
+ * (see enum eqr_domain_type), with a valid offset mask (up to 32 resets per
+ * domain).
+ *
+ * Domain types define expected behavior: one-register-per-reset,
+ * one-bit-per-reset, status detection method, busywait duration, etc.
+ *
+ * We use eqr_ as prefix, as-in "EyeQ Reset", but way shorter.

+ * The reset management module in the K230 SoC provides reset time control
+ * registers. For RST_TYPE_CPU0, RST_TYPE_CPU1 and RST_TYPE_SW_DONE, the period

+ * up to 255 * 0.25 = 63.75 µs. For RST_TYPE_FLUSH, the reset bit is
+ * automatically cleared by hardware when flush completes.
+ *
+ * Although this driver does not configure the reset time registers, delays have
+ * been added to the assert, deassert, and reset operations to cover the maximum
+ * reset time. Some reset types include done bits whose toggle does not
+ * unambiguously signal whether hardware reset removal or clock-stop period
+ * expiration occurred first. Delays are therefore retained for types with done
+ * bits to ensure safe timing.
