docs: printk-formats: Fix hex printing of signed values 



The commit cbacb5ab ("docs: printk-formats: Stop encouraging use of
unnecessary %h[xudi] and %hh[xudi]") obviously missed the point of sign
promotion for the signed values lesser than int. In such case %x prints
not the same as %h[h]x. Restore back those specifiers for the signed hex
cases.
