xen: change <asm/bug.h> to <xen/bug.h>
The idea of the patch is to change all <asm/bug.h> to <xen/bug.h> and
keep Xen compilable with adding only minimal amount of changes:
1. It was added "#include <xen/types.h>" to ARM's "<asm/bug.h>" as it
uses uint_{16,32}t in 'struct bug_frame'.
2. It was added '#define BUG_FRAME_STRUCT' which means that ARM hasn't
been switched to generic implementation yet.
3. It was added '#define BUG_FRAME_STRUCT' which means that x86 hasn't
been switched to generic implementation yet.
4. BUGFRAME_* and _start_bug_frame[], _stop_bug_frame_*[] were removed
for ARM & x86 to deal with compilation errors such as:
redundant redeclaration of ...
5. Remove BUG_DISP_WIDTH, BUG_LINE_LO_WIDTH, BUG_LINE_HI_WIDTH from
x86's <asm.bug.h> to not to produce #undef for them and #define again
with the same values as in <xen/bug.h>. These #undef and #define will
be anyway removed in the patch [2]
6. Remove <asm/bug.h> from <x86/acpi/cpufreq/cpufreq.c> and
<drivers/cpufreq/cpufreq.c> as nothing from <xen/bug.h> are used in
<*/cpufreq.c>
In the following two patches x86 and ARM archictectures will be
switched fully:
[1] xen/arm: switch ARM to use generic implementation of bug.h
[2] xen/x86: switch x86 to use generic implemetation of bug.h
