[PATCH v2] pmdomain: Use str_enable_disable-like helpers

shao.mingyin
2025-06-10T13:24:03Z

From: Shao Mingyin <shao.mingyin@zte.com.cn>

Replace ternary (condition ? "enable" : "disable") syntax and ternary
(condition ? "on" : "off") syntax with helpers from
string_choices.h because:
1. Simple function call with one argument is easier to read. Ternary
operator has three arguments and with wrapping might lead to quite
long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
file.
