    xen/arm: grant-table: Increased the initial number of grant frame to 4
    
    When a domain is created on ARM, the grant table code initialized one
    grant frame. With a basic load (i.e disk usage), Xen is quickly trying
    to expand the number of frames:
    
    (XEN) grant_table.c:1305:d2v0 Expanding dom (2) grant table from (1) to (2) 
frames.
    (XEN) grant_table.c:1305:d2v0 Expanding dom (2) grant table from (2) to (3) 
frames.
    (XEN) grant_table.c:311:d0v0 Increased maptrack size to 2 frames
    (XEN) grant_table.c:311:d0v0 Increased maptrack size to 3 frames
    
    The x86 code is initialied 4 frames (I didn't find the exact reason). I
    think we could use the same default value.
