It appears that the original commit 1e5de18278e6
("x86: Introduce GDT_ENTRY_INIT()") used bitwise operations on the parameters
when the commit 38e9e81f4c81 ("x86/gdt: Use bitfields for initialization")
changed them to simple castings. The latter change recently made sparse not
happy about. To satisfy it return to bitwise operations in GDT_ENTRY_INIT().
Fixes: 38e9e81f4c81 ("x86/gdt: Use bitfields for initialization")
