x86/boot/compressed: Avoid touching ECX in startup32_set_idt_entry()
Avoid touching register %ecx in startup32_set_idt_entry(), by folding
the MOV, SHL and ORL instructions into a single ORL which no longer
requires a temp register.
This permits ECX to be used as a function argument in a subsequent
patch.
