lib/coreboot_table: Add CBMEM_ID_VBOOT_WORKBUF pointer to coreboot table

Browse Source 
Since struct vb2_shared_data already contains workbuf_size and
vboot_workbuf_size is never used in depthcharge, remove it from struct
sysinfo_t. In addition, remove lb_vboot_workbuf() and add
CBMEM_ID_VBOOT_WORKBUF pointer to coreboot table with
add_cbmem_pointers(). Parsing of coreboot table in libpayload is
modified accordingly.

BRANCH=none
BUG=chromium:1021452
TEST=emerge-nami coreboot libpayload depthcharge; Akali booted correctly
