Subject: [PATCH] x86: add REQUIRED_MASK8

commit e38e05a85828dac23540cd007df5f20985388afc increased NCAPINTS to 9
but didn't add REQUIRED_MASK8 resulting in the following sparse warnings:

arch/x86/boot/cpustr.h:311:5: warning: undefined preprocessor identifier 'REQUIRED_MASK8'
arch/x86/boot/cpustr.h:314:5: warning: undefined preprocessor identifier 'REQUIRED_MASK8'
arch/x86/boot/cpustr.h:317:5: warning: undefined preprocessor identifier 'REQUIRED_MASK8'
arch/x86/boot/cpustr.h:320:5: warning: undefined preprocessor identifier 'REQUIRED_MASK8'
arch/x86/boot/cpustr.h:323:5: warning: undefined preprocessor identifier 'REQUIRED_MASK8'
