Gavin Shan 61659efdb3 drivers/base/memory: improve add_boot_memory_block()
Patch series "drivers/base/memory: Two cleanups", v3.

Two cleanups to drivers/base/memory.


This patch (of 2)L

It's unnecessary to count the present sections for the specified block
since the block will be added if any section in the block is present. 
Besides, for_each_present_section_nr() can be reused as Andrew Morton
suggested.

Improve by using for_each_present_section_nr() and dropping the
unnecessary @section_count.

No functional changes intended.
