platform/x86/amd/pmc: Use flex array when calling amd_pmc_stb_debugfs_open_v2()
Currently in amd_pmc_stb_debugfs_open_v2() the buffer size is assumed to
be fixed and a second call to amd_pmc_stb_debugfs_open_v2() may race with
a process holding open another fd. This could change "fsize" to a
bigger size causing an out of bounds read.
Instead create a struct with a flexarray to solve this.
