sh: Fix fallout from ZERO_PAGE consolidation
Consolidation of empty_zero_page declarations broke boot on sh.
sh stores its initial boot parameters in a page reserved in
arch/sh/kernel/head_32.S. Before commit 6215d9f4470f ("arch, mm:
consolidate empty_zero_page") this page was referenced in C code
as an array and after that commit it is referenced as a pointer.
This causes wrong code generation and boot hang.
Declare boot_params_page as an array to fix the issue.
