docs: printk-formats: Fix hex printing of signed values
The commit cbacb5ab0aa0 ("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.
