Add <asm/smp.h> for cpuid_to_hartid_map etc.
This is needed for both SMP and non-SMP builds, but not having it
causes a build error for non-SMP:
drivers/cpuidle/cpuidle-riscv-sbi.c: In function 'sbi_cpuidle_init_cpu':
drivers/cpuidle/cpuidle-riscv-sbi.c:350:26: error: implicit declaration of function 'cpuid_to_hartid_map' [-Werror=implicit-function-declaration]
Fixes: 6abf32f1d9 ("cpuidle: Add RISC-V SBI CPU idle driver")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
