Subject: [PATCH] ACPI: tables: Remove incorrect __nonstring attribute from table_sigs

The table_sigs array is declared as a 2D char array with a fixed size
(ACPI_NAMESEG_SIZE, which is 4). The use of the __nonstring attribute
here is unnecessary and triggers a compiler warning:

  warning: ‘nonstring’ attribute ignored on objects of type ‘const char[][4]’

Since GCC ignores this attribute on such declarations, and it causes
a build failure due to -Werror, remove __nonstring to fix the issue.
