Boottime: remove all block-related tunes including readahead size
With a request size fix, 2MB-sized readahead would not be a way to gain
boottime.
taimen - PVT - Hynix 128GB - boot_complete timestamp (avg of 100 loop)
Base [1] : 10.943
New [2] : 10.7495
taimen - PVT - Hynix 128GB - boot_complete timestamp + fastboot -w (avg of 100 loop)
Base [1] : 32.5857
New [2] : 31.7474
[1] w/o this CL, revert commit 7c37954411e9 ("mm: readahead back to 128KB")
[2] w/ this CL, keep commit 7c37954411e9 ("mm: readahead back to 128KB")
